GENERALIZATION OF HYSTERESIS MODELING TO ANISOTROPIC AND TEXTURED MATERIALS

A generalized model has recently been developed to incorporate the eff ects of anisotropy and texture into the description of hysteresis. It is shown that these two effects can be incorporated into the model sim ply through changes in the anhysteretic magnetization. In this paper, the new model is used to fit several sets of experimental hysteresis l oops. The generalized model has been used to describe the magnetizatio n curves of soft and especially hard magnetic materials. The latter no rmally exhibit high anisotropy and are often highly textured, which pr eviously had made them difficult to model accurately within the confin es of the restricted isotropic model. The results show significant imp rovement of the generalized model over the previous isotropic model. ( C), 1998 Elsevier Science B.V. All rights reserved.
