Peculiarities of magnetic state of high-anisotropy ferromagnets after large Barkhausen discontinuity

In order to study the peculiarities of the ferromagnet magnetic state following the jump-wise remagnetization, monocrystalline plates of the SmCosub(4.3)Cusub(0.7) have been selected. The magnetization processes in the H long c field have been studied. It is shown that as a result of the jump-wise magnetization, the structure of the large ramified domains is being formed. The results of the peculiar domain structure formation are displayed in the easier process of the domain boundaries shifting. Two possible explanations of the observed process of the domain boundaries shifting are given
