Uaea Alloy Magnetic vaivai Ni77mo4cu5

Fa'amatalaga Puupuu:

(Soi maneta vaivai)

Ni77mo4cu5 o se nickel-uʻamea mageta alloy, e tusa ma le 80% nickel ma 20% uʻamea mea. Fausia i le 1914 e le physicist Gustav Elmen i Bell Telephone Laboratories, e iloga ona o lona maualuga tele o le maneta, lea e aoga ai e avea o se mea faʻamaneta i mea eletise ma mea faʻaeletoroni, faʻapea foʻi ma le talipupuni mageta e poloka ai maneta. u'amea permalloy fa'apisinisi e masani ona i ai le fa'aogaina o le 100,000, fa'atusatusa i le tele o afe mo u'amea masani.
I le faaopoopo atu i le maualuga maualuga, o isi mea maneta e maualalo le coercivity, latalata i le zero magnetostriction, ma le taua o le anisotropic magnetoresistance. O le maualalo o le magnetostriction e taua tele mo mea tau alamanuia, e mafai ai ona fa'aoga i ata manifinifi lea e mafai ai ona fa'atupuina le fa'alavelave fa'aletonu i se suiga tele i mea maneta. Ole malosi ole eletise ole Permalloy e mafai ona fesuisuiai pe a ma le 5% e fuafua ile malosi ma le itu ole fa'aogaina ole maneta. Permalloys e masani lava ona i ai foliga fa'atotonugalemu fausaga tioata tioata ma se lattice tumau e tusa ma le 0.355 nm i le va o se nickel concentration o 80%. O se fa'aletonu o le permalloy e le matua'i ma'ale'ale pe fa'aogaina, o lea la o talosaga e mana'omia ai foliga fa'apitoa, e pei o talita fa'amaneta, e faia i isi u'amea maualuga maualuga e pei o le mu metal. Permalloy e faʻaaogaina i laminations transformer ma ulu faʻamaumau maneta.
Ni77mo4cu5 fa'aaogaina lautele i le leitio-eletise alamanuia, meafaifaaili sa'o, fa'atonu mamao ma le fa'aogaina otometi.
