Residual Magnetization and Magnetostriction of Nickel Single Crystals

抄録

By use of long cylindrical single crystals of pure nickel with various crystallographic orientations, magnetization and magnetostriction were measured at room temperature. It was found that the remanent magnetization I_r is given approximately by the following relation: I_r⁄I_s=1⁄\sqrt3β₁, where I_s is the saturation magnetization and β₁ is the direction cosine of the rod axis with respect to the nearest [100] direction. On the basis of this relation the magnetostriction constants and also the crystal anisotropy constants were determined. Magnetostriction curves constructed theoretically from the obtained values of magnetostriction constants agree with the experimental curves.
