摘要：

The experimental set-up allows to store the measured data and the energy losses per cycle are calculated. The experimental results are compared with the simulated ones obtained in the dynamic Preisach model. The influences of the Bi2O3 content and of the excitation frequency on the magnetic properties are discussed; an optimum amount of impurities is found. (C) 1999 Elsevier Science B.V.
