(I-alloy ethambile yamagnetic)

I-Ni77mo4cu5 iyi-alloy yamagnetic ye-nickel-iron, enokuqukethwe kwe-nickel okungaba ngu-80% kanye no-20% wensimbi. Yasungulwa ngo-1914 yisazi sesayensi uGustav Elmen eBell Telephone Laboratories, iphawuleka ngokuvuleka kwayo okuphezulu kakhulu kwamagnetic, okwenza ibe wusizo njengezinto eziyinhloko zamagnetic emishinini kagesi neye-elekthronikhi, kanye nasekuvikeleni kwamagnetic ukuvimba amasimu amagnetic. Ama-alloy e-permalloy ezentengiselwano ngokuvamile anokuvuleka okulinganiselwe okungaba ngu-100,000, uma kuqhathaniswa nezinkulungwane eziningana zensimbi evamile.
Ngaphezu kokungena okuphezulu, ezinye izakhiwo zayo zamagnetic yi-coercivity ephansi, i-magnetostriction eseduze ne-zero, kanye ne-anisotropic magnetoresistance ebalulekile. I-magnetostriction ephansi ibalulekile ekusetshenzisweni kwezimboni, okuvumela ukuthi isetshenziswe kumafilimu amancane lapho ukucindezeleka okuguquguqukayo bekungabangela khona ukwehluka okukhulu kakhulu kwezakhiwo zamagnetic. Ukumelana kukagesi kwe-Permalloy kungahluka kuze kufike ku-5% kuye ngamandla kanye nesiqondiso sensimu yamagnetic esetshenzisiwe. Ama-Permalloy ngokuvamile anesakhiwo sekristalu le-cubic esisebusweni esinokuqina kwe-lattice okungaba ngu-0.355 nm eduze kwe-nickel concentration engu-80%. Ububi be-permalloy ukuthi ayiguquki kakhulu noma ayisebenzi, ngakho-ke izinhlelo zokusebenza ezidinga izimo eziyinkimbinkimbi, njengezihlangu zamagnetic, zenziwe ngezinye izinsimbi zokungena okuphezulu njengensimbi ye-mu. I-Permalloy isetshenziswa kuma-transformer laminations kanye namakhanda okuqopha amagnetic.
I-Ni77mo4cu5 isetshenziswa kabanzi embonini ye-radio-electronic, izinsimbi zokunemba, isilawuli kude kanye nesistimu yokulawula okuzenzakalelayo.
