HYSTERESIS LOOPS OF UNTAXIAL FERROMAGNETIC FILMS (Petli Gisterezisa Ferromagnitnykh Plenok),

Abstract

All the multiformity of hysteresis loops of uniaxial film elements can be described on the basis of a rotation model. Equations for all the classes of hysteresis loops under examination are presented. The closest congruity of the theory based on the rotation model with the experiment is observed under specimens with similar vof coercive force for wall shiftings and for rotations. The experimental manifestation of processes of wall shifting are more graphically and easily carried out by examining the hodograph of magnetization. In all the cases investigated, the magnetic reversal of film elements is accompanied by domain forma tion. The share of the processes of wall shifting is minimal through the action of the external field near the heavy direction of magnetization. With magnetic reversal of the film element exactly along the light direction and exactly along the left direction of the magnetization processes, rotation of the magnetic moment of the specimen is not observed.
