Tha an anisotropachd magnetach a\u2019 ciallachadh gu bheil stuth aig sti\u00f9ireadh ro-phr\u00ecomh airson a mh\u00f2ran magnetach nuair a chuireas tu raon magnetach air. Ann an teacsa nas s\u00ecmplidh, tha e a\u2019 ciallachadh gu bheil d\u00f2igh a tha stuth air a sti\u00f9ireadh a\u2019 toirt buaidh air mar a dh\u2019obraicheas e gu magnetach. Tha cuid de stuthan ag iarraidh a bhith magnetachadh nas motha ann an sti\u00f9ireadh s\u00f2nraichte na feadhainn eile. Bidh sinn a\u2019 gairm sin an \u201ceas\u201d axis.

Adhbharan airson Anisotropachd Magnetach<\/strong><\/span><\/h2>\n

Tha d\u00e0 rud a\u2019 toirt adhbhar airson anisotropachd magnetach.<\/p>\n

    \n
  1. Structar Crystalline: <\/strong>Faodaidh co-chothromachd na cruth-crystalline de stuth cruthachadh axis furasta. Bidh stuthan c\u00f9bach gu tric ag iarraidh am magnetachadh a sti\u00f9ireadh air an diagonal bodhaig. Tha stuthan nach eil c\u00f9bach ag iarraidh am magnetachadh a sti\u00f9ireadh air cuid de chothromach cruth-crystalline. Bidh sinn a\u2019 gairm seo an anisotropachd magnetocrystalline. Is e seo an aon adhbhar n\u00e0darra airson anisotropachd oir tha e a\u2019 tighinn bho structar na stuth.<\/li>\n
  2. Anisotropachd Cruth:<\/strong> Nuair a tha thu a\u2019 faighinn nithean neo-spheric mar bhideothan tana no p\u00ecosan beaga, faodaidh tu anisotropachd fhaighinn oir de bhuaidhean uachdar no oir a\u2019 ch\u00f2rr. Tha cruth na stuth a\u2019 toirt buaidh air mar a tha e a\u2019 freagairt ri raon magnetach taobh a-muigh. Tha raointean demagnetizing eadar-dhealaichte a r\u00e8ir an d\u00f2igh a thomhais thu iad.<\/li>\n
  3. Ceangal Spin-Orbit: <\/strong>Faodaidh an eadar-obrachadh eadar rothladh nan dealanan agus gluasad nan dealanan timcheall air an niuclas a dh\u00e8anamh gum bi am magnetachadh ag iarraidh puing a chur ann an sti\u00f9ireadh s\u00f2nraichte.<\/li>\n
  4. Anisotropy Magnetoelastic:<\/strong> Ma chuireas tu cuideam meacanaigeach no teannachadh air stuth, faodaidh tu atharrachadh mar a tha e a\u2019 gi\u00f9lan gu magnetach.<\/li>\n
  5. Anisotropy Eadar-eadarachaidh:<\/strong>Tha seo a\u2019 buntainn ris na h-eadar-obrachadh eadar na mionaid magnetach anns na stuthan. Nuair a tha stuthan ferromagnetic agus antiferromagnetic ceangailte ri ch\u00e8ile, faodaidh an c\u00f2mhdach antiferromagnetic buaidh a thoirt air mar a tha am magnetachadh a\u2019 gi\u00f9lan anns an c\u00f2mhdach ferromagnetic.<\/li>\n
  6. D\u00f2pan agus Salachar:<\/strong> Faodaidh tu salachar no lochdan a thoirt a-steach gu d\u00f9rachdach ann an stuth gus atharrachadh a dh\u00e8anamh air an structar dealanach aige, a dh\u2019 fhaodadh buaidh a thoirt air mar a tha e a\u2019 gi\u00f9lan gu magnetach agus air a anisotropy.<\/li>\n
  7. Teannachadh:<\/strong> Nuair a n\u00ec thu deformachadh meacanaigeach air stuth, bidh thu a\u2019 cur bacadh air co-sheirm structar criostail. Faodaidh an bacadh seo atharrachadh far a bheil an axis furasta agus mar a tha e a\u2019 gi\u00f9lan gu magnetach.<\/li>\n<\/ol>\n

    Se\u00f2rsan Anisotropy Magnetach<\/strong><\/span><\/h2>\n

    Tha beagan she\u00f2rsaichean eadar-dhealaichte de anisotropy magnetach ann.<\/p>\n

      \n
    1. Anisotropy Criostalach:<\/strong>Is e seo nuair a tha co-sheirm criostail an stuth a\u2019 dearbhadh far a bheil an axis furasta. Faodaidh tu seo fhaicinn ann an stuthan ci\u00f9bach agus neo-ci\u00f9bach.<\/li>\n
    2. Anisotropachd Cruth:<\/strong> Is e seo nuair a tha cumadh an stuth a\u2019 dearbhadh far a bheil an axis furasta. Ch\u00ec thu seo ann am filmichean tana agus nanoparticulan.<\/li>\n
    3. Magnetostrictachd:<\/strong> Is e seo nuair a bhios magnetachd an stuth a\u2019 eadar-obrachadh leis an structar lattice, agus bidh an stuth a\u2019 leudachadh no a\u2019 teannachadh nuair a chuireas tu raon magnetach ris.<\/li>\n
    4. Anisotropy Raon Magnetach: Is e seo nuair a tha susceptibilty magnetach \u00e0rd aig an stuth, agus bidh an raon magnetach a-muigh a\u2019 eadar-obrachadh gu eadar-dhealaichte leis na mionaid magnetach anns an stuth a r\u00e8ir d\u00e8 an taobh a tha am raon a\u2019 comharrachadh.<\/li>\n<\/ol>\n

      <\/h2>\n

      Anisotropy ann an Stuthan Magnetach Cruaidh agus Bog<\/strong><\/span><\/h2>\n

      Stuthan Magnetach Cruaidh: <\/strong>Na stuthan seo, leithid m\u00f2ranagan neodymium<\/span><\/a>, tha an anisotropachd magnetach \u00e0rd aca, mar sin tha iad resistant ri demagnetization. Bidh sinn a\u2019 cleachdadh an n\u00e0dar l\u00e0idir, sti\u00f9irichte de na magnetan ann an tagraidhean leithid motaran agus gineadairean.<\/p>\n

      Stuthan Magnetach Bog:<\/strong> Gu tric, faodaidh stuthan magnetach bog cuideachd a bhith anisotropic air sg\u00e0th factaran structarail taobh a-staigh no d\u00f2ighean giullachd taobh a-muigh. Tha eisimpleirean a\u2019 gabhail a-steach st\u00e0ilcean dealain le gr\u00ecnean a chaidh an sti\u00f9ireadh a chleachdadh ann an tionndaidhean.<\/p>\n

      \u00a0<\/strong><\/p>\n

      G\u00e8illeadh nas fhe\u00e0rr ri anisotropachd magnetach<\/strong><\/span><\/h2>\n

      Faodaidh luchd-d\u00e8anamh adhartachadh an anisotropachd magnetach le bhith a\u2019 smachdachadh grunn fhactaran r\u00e8 a\u2019 ghn\u00ecomhachais:<\/p>\n

      Taghadh Stuth: <\/strong>Tha an taghadh de stuth bunaiteach, leithid neodymium ann an magnetan \u00e0rd-ch\u00e0ileachd, cudromach airson feartan magnetach l\u00e0idir fhaighinn.<\/p>\n

      D\u00f2ighean sti\u00f9iridh agus giullachd: <\/strong>Nuair a n\u00ec sinn am magnet, bidh sinn a\u2019 sti\u00f9ireadh na mion-chinnidhean magnetach le bhith a\u2019 cleachdadh pr\u00f2iseasan leithid br\u00f9thadh teth no br\u00f9thadh isostatic. Bidh seo a\u2019 cuideachadh le bhith a\u2019 d\u00e8anamh magnetan le feartan anisotropic nas fhe\u00e0rr.<\/p>\n

      Meud agus Cruth Grian: <\/strong>Tha smachd math againn air meud agus cruth na grian den stuth gus d\u00e8anamh cinnteach gu bheil feartan magnetach seasmhach aige.<\/p>\n

      Susbaint ocsaidean: <\/strong>L\u00f9ghdaich sinn an \u00e0ireamh de ocsaidean r\u00e8 a\u2019 ghn\u00ecomhachais gus am bi an stuth a\u2019 sruthadh nas fhe\u00e0rr agus an anisotropachd a chumail suas.<\/p>\n

      Br\u00f9thadh d\u00ecreach fo raon magnetach:<\/strong> Bidh sinn a\u2019 sti\u00f9ireadh na mion-chinnidhean magnetach nuair a bhr\u00f9th sinn am stuth r\u00e8 a\u2019 ghn\u00ecomhachais. Sin mar a gheibh sinn an anisotropachd anns an toradh mu dheireadh.<\/p>\n

      \u00a0<\/strong><\/p>\n

      Magnetan anisotropic vs. isotropic<\/strong><\/span><\/h2>\n

      Magnetan anisotropic: <\/strong>Tha na magnetan seo le feartan magnetach a tha an urra ris an sti\u00f9ireadh. Mar eisimpleir, n\u00ec sinn magnetan neodymium sintered a tha na grianan air an sti\u00f9ireadh r\u00e8 a\u2019 ghn\u00ecomhachais. Tha seo a\u2019 toirt dhaibh coileanadh magnetach l\u00e0idir ann an sti\u00f9ireadh s\u00f2nraichte.<\/p>\n

      Magnets Isotropic:<\/strong> An coimeas, chan eil magnets isotropic mar magnets neodymium ceangailte gu s\u00f2nraichte airson sti\u00f9ireadh magnetization. Tha iad coltach ri feartan magnetach ann an gach sti\u00f9ireadh. Leigidh seo leat an cruthachadh agus an magnetachadh ann an diofar shuidheachaidhean. Gu bunaiteach, tha iad nas laige na magnets anisotropic.<\/p>\n

      Tagraidhean de Magnets Anisotropic<\/strong><\/span><\/h2>\n

      Tha iomadh cleachdadh aig magnets anisotropic ann an diofar ghn\u00ecomhachasan oir tha iad nas l\u00e0idire agus le sti\u00f9ireadh soilleir. Seo beagan eisimpleirean:<\/p>\n

        \n
      1. L\u00e0raich: <\/strong>Bidh sinn a\u2019 cleachdadh magnets anisotropic, mar magnets samarium cobalt, ann an l\u00e0raich a bhios a\u2019 tionndadh raointean magnetach gu comharran dealain. Gheibh thu na l\u00e0raich seo ann an siostaman c\u00e0r agus adhair.<\/li>\n
      2. Gineadairean: <\/strong>Bidh sinn a\u2019 cleachdadh raon magnetach a chruthaicheas magnets anisotropic gus gineadairean a dh\u00e8anamh. Mar eisimpleir, tha magnets anns na l\u00f9ban ghaoth anisotropic.<\/li>\n
      3. Re\u00f2thadaireachd:<\/strong> Tha rannsachadh ga dh\u00e8anamh air cleachdadh magnets ann an re\u00f2thadaireachd. Mar eisimpleir, tha MIT ag obair air cleachdadh magnets mar re\u00f2thadair comasach.<\/li>\n
      4. N\u00e0darra Magnetach N\u00faicleach (NMR): <\/strong>Bidh sinn a\u2019 cleachdadh magnets anisotropic gus speactrometers NMR a dh\u00e8anamh. Leigidh na h-innealan seo le ar sgr\u00f9dadh a dh\u00e8anamh air feartan corporra agus ceimiceach stuthan.<\/li>\n
      5. Tagraidhean Mheidigeach: <\/strong>Tha magnets anisotropic seasmhach aig te\u00f2thachd \u00e0rd, mar sin bidh sinn a\u2019 cleachdadh iad ann an innealan meidigeach sterilizable agus implantachan.<\/li>\n<\/ol>\n

        Tha fiosrachadh mu magnetach anisotropy a\u2019 cuideachadh le bhith a\u2019 cleachdadh magnets gu h-\u00e0rd-\u00f9rlar ann an doigh s\u00f2nraichte. Tha sti\u00f9ireadh aig magnets anisotropic, agus tha sin cudromach. Sin as coireach gu bheil iad air an cleachdadh ann an iomadh gn\u00ecomhachas, bho l\u00f9th gu c\u00f9ram sl\u00e0inte. Tha magnets isotropic a\u2019 toirt barrachd s\u00f9bailteachd ann an dealbhadh ach chan eil iad cho l\u00e0idir. Ma tha thu ag iarraidh barrachd fiosrachaidh mu stuthan magnetach agus mar a dh\u2019fhaodadh iad do chuideachadh, cuir fios thugainn aig \u00e0m sam bith.<\/p>\n
