Abstract
Results of an experimental study of symmetrical and asymmetric loops of magnetic hysteresis in weak ac fields are given (Rayleigh region). The asymmetric loops are observed when a dc magnetizing field is additionally applied to the ferromagnetic material together with a weak ac field. The studies have been carried out on a manganese-zinc ferrite of grade M1000NM-A. It has been shown that the symmetrical hysteresis loops obey the mathematical Rayleigh model by no means strictly. It has been revealed that if the dc magnetizing field is in the Rayleigh region, then the hysteresis loops in the ac field remain symmetrical as before. But if the dc field falls outside the Rayleigh region, then the hysteresis loops become asymmetric. This asymmetry is caused by the different values of the remanences on the ascending and descending branches of the hysteresis loop with the same quadratic dependence of magnetization on the field as in the Rayleigh case.
