Tsanangudzo Yesimba
Neodymium isantiferromagnetic simbi inoratidza magineti maitiro kana yakachena, asi patembiricha iri pasi pe19 K (254.2 °C; 425.5 °F).Neodymium maumbirwo ane ferromagnetic shanduko simbi sesimbi, ine Curie tembiricha iri pamusoro pekamuri tembiricha, inoshandiswa kugadzira neodymium magineti.
Neodymium magnets 'simba musanganiswa wezvinhu zvakasiyana.Chinonyanya kukosha ndeyepamusoro uniaxial magnetocrystalline anisotropy ye tetragonal Nd2Fe14B crystal structure (HA 7 T - magnetic field simba H mumayuniti eA/m kurwisana nemagnetic moment muAm2).Izvi zvinoratidza kuti kristaro yezvinhu inobata magineti zvakanaka pamwe chete neimwe crystal axis asi inoona zvichinetsa zvakanyanya kuita magineti mune mamwe maitiro.Iyo neodymium magineti alloy, semamwe magineti, inogadzirwa nemicrocrystalline tsanga dziri panguva yekugadzira dzakarongeka mune yakasimba magineti zvekuti magineti axes adzo anonongedza munzira imwechete.Komboni yacho ine yakanyanyisa kumanikidzana, kana kuramba demagnetization, nekuda kwekuramba kwecrystal lattice kushandura kwairi kuita magineti.
Nekuti ine maerekitironi mana asina kupetwa muchimiro chayo erekitironi sekuenzanisa ne (paavhareji) matatu musimbi, atomu ye neodymium inokwanisa kuve neakakosha magineti dipole nguva.Maerekitironi asina kupetwa ari mugineti anorongeka kuitira kuti ma spins awo akatarisana negwara rimwe chete anoburitsa magineti.Izvi zvinoguma mune yakasimba saturation magnetization yeNd2Fe14B musanganiswa (Js 1.6 T kana 16 kG) uye yakajairwa yakasara magineti ye1.3 teslas.Nekuda kweizvozvo, iyi magineti chikamu inokwanisa kuchengetedza huwandu hwakakosha hwesimba remagineti (BHmax 512 kJ/m3 kana 64 MGOe), sezvo huwandu hwesimba hwepamusoro hunoenderana neJs2.
Iyi magineti simba kukosha kwakatenderedza 18 nguva nevhoriyamu uye 12 nguva nehukuru hukuru kupfuura "nguva dzose"ferrite magineti. Samarium cobalt (SmCo), yekutanga inotengeswa isingawanzo-yepasi magineti, ine yakaderera mwero weiyi magineti simba ficha pane NdFeB alloys.Neodymium magineti 'magineti maitiro anonyatso kukanganiswa neiyo alloy's microstructure, kugadzira maitiro, uye kuumbwa.
Maatomu esimbi uye neodymium-boron musanganiswa unowanikwa mune dzimwe nhanho mukati meNd2Fe14B crystal chimiro.Iyo diamagnetic boron maatomu anosimudzira kubatana kuburikidza neakasimba covalent zvisungo asi hazvibatsire zvakananga kune magineti.Neodymium magineti haadhure kupfuura samarium-cobalt magineti nekuda kweiyo yakaderera isingawanzo kudzika pasi (12% nevhoriyamu, 26.7% nehukuru), pamwe nekuwanikwa kweneodymium nesimbi zvichienzaniswa nesamarium necobalt.
