(Cov hlau nplaum mos mos)

Ni77mo4cu5 yog ib qho hlau nplaum nickel-hlau, nrog kwv yees li 80% nickel thiab 20% hlau. Tsim tawm xyoo 1914 los ntawm tus kws kho mob Gustav Elmen ntawm Bell Telephone Laboratories, nws yog qhov tseem ceeb rau nws qhov permeability siab heev, uas ua rau nws muaj txiaj ntsig zoo li cov khoom siv hlau nplaum hauv cov khoom siv hluav taws xob thiab hluav taws xob, thiab tseem nyob rau hauv kev tiv thaiv hlau nplaum los thaiv cov teb hlau nplaum. Cov hlau nplaum permalloy lag luam feem ntau muaj permeability kwv yees li ntawm 100,000, piv rau ntau txhiab rau cov hlau ib txwm muaj.
Ntxiv rau qhov muaj permeability siab, nws lwm yam khoom sib nqus yog qhov tsis tshua muaj coercivity, ze li xoom magnetostriction, thiab qhov tseem ceeb anisotropic magnetoresistance. Qhov qis magnetostriction yog qhov tseem ceeb rau kev siv hauv kev lag luam, tso cai rau nws siv rau hauv cov yeeb yaj kiab nyias uas qhov kev ntxhov siab sib txawv yuav ua rau muaj kev hloov pauv loj heev hauv cov khoom sib nqus. Permalloy lub zog hluav taws xob resistivity tuaj yeem sib txawv ntau txog 5% nyob ntawm lub zog thiab kev coj ntawm lub teb sib nqus siv. Permalloys feem ntau muaj lub ntsej muag nruab nrab cubic siv lead ua qauv nrog lub lattice tas li ntawm kwv yees li 0.355 nm nyob ze ntawm nickel concentration ntawm 80%. Qhov tsis zoo ntawm permalloy yog tias nws tsis yog ductile lossis ua haujlwm tau, yog li cov ntawv thov uas xav tau cov duab zoo nkauj, xws li cov hlau nplaum sib nqus, yog ua los ntawm lwm cov hlau nplaum permeability siab xws li mu hlau. Permalloy yog siv rau hauv transformer laminations thiab cov taub hau sau magnetic.
Ni77mo4cu5 siv dav hauv kev lag luam xov tooj cua-hluav taws xob, cov cuab yeej siv precision, kev tswj chaw taws teeb thiab kev tswj tsis siv neeg.
