Magnetostriction and Crystal Anisotropy of Nickel-Chromium and Nickel-Vanadium Alloys

概要

Magnetostriction constants, λ_<100> and λ_<111>, of nickel-chromium and nickel-vanadium alloys were measured at room and liquid nitrogen temperatures by a strain gauge method. Both constants were negative and their magnitudes decreased monotonically with increasing the composition of adding elements. Magnetocrystalline anisotropy constants were also measured at the same temperatures. The concentration dependence of the anisotropy constants was more drastic than that of the magnetostriction constants. The present data and other available data of nickel binary alloys were analysed on the basis of Neel's theory and the coefficients of dipole-dipole and quadrupole-quadrupole interactions of atom pairs in nickel alloys were estimated. The dipole-dipole interactions of Ni-M (where M = V, Cr, Mn, Fe, Co, Ni and Cu) atom pairs were fairly well explained under the assumption of the spin-orbit interaction.
