Abstract

The hysteresis of frequency-field dependence was experimentally investigated and these data compared with the local hysteresis curves of magnetization for epitaxial films and bulk monocrystal plates BaFe₁₂O₁₉. It is shown that these data are correlated and the measured values of the fields of break H_br are coincided in both cases. It is found that the phenomenon of hysteresis FMR was caused by the delay of generation and growth of magnetic reversal centers. It was offered to use the character of transition from the saturated region to one domain as a criterion of the epitaxial films quality.
