Magnetization of Nickel Single Crystals

Abstract

A calculation of the magnetization curves of nickel single crystals is made by the method of Lawton and Steward for arbitrary orientation of the crystal in the field. The anisotropy coefficients are calculated from experimental curves with the applied field in symmetry directions, and it is found that only K₁ can be determined reliably with the data used. The calculated off‐axis curves agree well with experimental results. A correcting field determined from the easy‐axis magnetization curve is utilized to compensate for internal strain effects. The relation between the calculated field minus the observed field and the easy‐axis field suggests a possible method for measuring internal strain energy in ferromagnetic crystals.
