anisotropy constant
All Answers (11) 1  See for example J. M. D. Coey, Magnetism and magnetic materials. 2  The anisotropy constant expresses a measure of how different the longitudinal magnetization is from the transverse magnetization for an anisotropically magnetized medium. 3  The shape of an M(H) curve may depend on many things. 4  Well said, Werner.
