Izibuthe ze-NdFeB, zingozibuthe bomhlaba ezingavamile ezisetshenziswa kakhulu ezinhlobonhlobo zezimboni nezohwebo ngenxa yezakhiwo zazo ezinhle kakhulu kazibuthe.Laba zidonsa baziwa ngamandla abo aphezulu, ukumelana nokukhishwa kazibuthe, kanye nezindleko eziphansi uma kuqhathaniswa, okubenza babe ukukhetha okudumile kwezinhlobonhlobo zemishini kagesi, izinsiza zezokwelapha, nemishini.
Isakhiwo seIzibuthe ze-NdFeBiyinkimbinkimbi impela, kodwa yilokhu kuyinkimbinkimbi okubanikeza izici zabo eziyingqayizivele.Lawa mazibuthe enziwe ngenhlanganisela ye-neodymium, insimbi, ne-boron, enenani elincane lezinye izakhi ukuze kuthuthukiswe izakhiwo zazo kazibuthe.Ukhiye wamandla ayo azibuthe akhethekile usekuhlelekeni kwama-athomu ngaphakathi kwesakhiwo sekristalu lento.
Isakhiwo sekristalu seIzibuthe ze-NdFeBi-tetragonal lattice lapho i-neodymium ne-boron athomu zakha izingqimba ngaphakathi kwesakhiwo se-lattice kanye nama-athomu ensimbi athatha izikhala phakathi kwalezi zingqimba.Lolu hlelo oluyingqayizivele lwama-athomu luqondanisa izikhathi zikazibuthe zama-athomu, kwakheka insimu enamandla kazibuthe.
Ngaphezu kwesakhiwo sabo esiyingqayizivele sekristalu,Izibuthe ze-NdFeBavame ukwakhiwa ngezinhlobonhlobo zomumo nosayizi, okuhlanganisa amashidi, amadiski, namabhulokhi, ukuze afanele izinhlelo zokusebenza ezahlukene.Ngokuqondene,Ingxenye Ndfeb ozibuthezisetshenziswa kakhulu ekukhiqizeni amamotho, amajeneretha, izihlukanisi kazibuthe kanye nemishini ye-magnetic resonance imaging (MRI) ngenxa yamandla amakhulu kazibuthe nokuzinza.
Kafushane, ukwakheka kozibuthe be-NdFeB kuyisici esibalulekile kuzakhiwo zabo ezinhle kakhulu kazibuthe.I-tetragonal lattice, ehlanganiswe nokuhlelwa okunembile kwe-neodymium, i-athomu ye-iron ne-boron, ivumela lawa mamagnethi ukuthi abonise amandla kazibuthe aphezulu kanye nokumelana nokukhishwa kazibuthe. Ingxenye Ndfeb ozibuthe, ikakhulukazi, iyingxenye ebalulekile ezinhlobonhlobo zezimboni nezentengiso ezidinga izinkambu kazibuthe eziqinile nezizinzile.
