Zithunzi za Honsen Magneticsamagulitsa maginito ovomerezeka a neodymium.A neodymium maginito (amatchedwanso NdFeB NIB kapena Neo maginito) ambiri ankagwiritsa ntchito mtundu osowa-dziko lapansi maginito, ndi maginito okhazikika opangidwa ndi aloyi wa neodymium, chitsulo ndi boron kupanga Nd2Fe14B tetragonal crystalline dongosolo.Yopangidwa mu 1982 ndi General Motors ndi Sumitomo Special Metals, maginito a neodymium ndi amphamvu kwambiri maginito okhazikika omwe amapezeka pamalonda.Asinthanso mitundu ina ya maginito pamagwiritsidwe ambiri muzinthu zamakono zomwe zimafunikira maginito amphamvu okhazikika, monga ma motors mu zida zopanda zingwe, ma hard disk drive ndi maginito zomangira.Simukudziwa ngati Neodymium ndiye chinthu chabwino kwambiri pakugwiritsa ntchito kwanu?Dinani apa kuti mufananize ndi mawonekedwe ndi kufananitsa kwazinthu zonse zamaginito zomwe timapereka.
Neodymium yozungulira maginito okhazikika Kufotokozera
Kapangidwe ka kristalo ka tetragonal Nd2Fe14B kumakhala ndi maginito apamwamba kwambiri a uniaxial magnetocrystalline anisotropy(HA~7 teslas-magnetic field mphamvu H mu A/m motsutsana ndi maginito mu A.m2).Izi zimapatsa chigawocho kuthekera kokhala ndi mphamvu zambiri (ie, kukana kukhala ndi demagnetized).Chigawochi chimakhalanso ndi maginito apamwamba kwambiri (Js ~ 1.6 T kapena 16 kG) ndipo kawirikawiri 1.3 teslas. Choncho, monga momwe mphamvu zowonjezera mphamvu zimayenderana ndi js2, gawo la maginitoli likhoza kusunga mphamvu zazikulu za maginito (BHmax ~ 512). kJ/m3 kapena 64 MG·Oe) Katunduyu ndi wapamwamba kwambiri mu ma aloyi a NdFeB kuposa maginito a samarium cobalt (SmCo), omwe anali mtundu woyamba wa maginito osowa padziko lapansi kugulitsidwa.M'malo mwake, maginito a maginito a neodymium amadalira kapangidwe ka alloy, microstructure, ndi njira yopangira yomwe imagwiritsidwa ntchito.n45 neodymium maginito chimbale
