Abstract

Disk-shaped single crystal specimens with a (001) plane and rod-shaped polycrystal specimens were prepared from Ni–Mn–Fe alloys containing less than about 29% manganese and less than about 25% iron. Measurements of the crystal magnetic anisotropy K₁ and the saturation magnetostriction λ_s were carried out for the specimens which were cooled from 650°C at a rate 26°C/sec after high-temperature heating. The absolute value of K₁ increased with increasing iron concentration and then decreased steadily after passing through a maximum. The absolute value of λ_s decreased rapidly with increasing manganese and iron concentrations, reached zero value at nickel concentrations a little higher than Ni₃(Mn, Fe), and then increased gradually. In a Ni–Mn–Fe alloy of about 20% manganese and about 5% iron that exhibits the highest permeability, the values of K₁ and λ_s are fairly small. As is the case with Ni–Mn alloys, it is considered that the high permeability of the alloy comes from the very small values of K₁ and λ_s.
