Reversible Properties of Polycrystal-Line Ferromagnets -- II. Experimental Variation of the Reversible Susceptibility and Q with Magnetization

摘要

The reversible susceptibility and the differential magnetostriction of ferromagnetic and ferromagnetic material has been considered, from a statistical standpoint in a previous paper, which will be designated I wherever referred to in this present paper.n The magnetic Q is considered to be the ratio of the real to imaginary part of the reversible susceptibility when that susceptibility is measured at a finite frequency. The present paper considers the variation with magnetization of Q for biasing and differential fields parallel and normal respectively.
