Anisotropy parameters and coercivity for sintered Co5Sm permanent magnet alloys

Abstract
Saturation magnetization, intrinsic coercive force,anisotropy field, and anisotropy constants were determined for a sample of sintered Co5Sm at 4.2, 77, 300, and 500 °K. The ralationship between the temperature dependence of the coercivity and the anisotropy parameters is discussed.
