materials with similar magnetic properties are supermalloy , supermumetal, nilomag, sanbold, Molybdenum Permalloy , Ultraperm, M-1040, etc. Heusler alloy A Heusler alloy is a ferromagnetic metal alloy based on a Heusler phase. Heusler phases are intermetallics with particular composition and fcc crystal structure. They are ferromagnetic even though the constituting elements
