MACROSCOPIC ANALYSIS OF MAGNETIC TRANSITIONS IN ANISOTROPIC MAGNETIC MATERIALS

Abstract
The analysis of a macroscopical description, in terms of anisotropy constants, of some magnetic transitions in uniaxial systems is presented. The magnetic processes considered are the saturation along a hard direction and the first order magnetization process (FOMP). Evidence is given that a phenomenological description can offer some advantages in the physical interpretation of the mechanisms at the origin of the processes. The occurrence of FOMP is found to be consistent with the small angle canting model.
