| Popis: | The possibility of decomposing the quasi-static hysteresis loop to the contributions of the rotational magnetization (DR) and the domain wall movement (DWM) is demonstrated experimentally and modelled theoretically by the hyperbolic T model. Although the method of decomposition described here is quite general for ferromagnetic materials, it is ideally applicable to the Finemet-type nanocrystalline alloys because of the presence of the strongly overlapping DR and DWM processes in the low and intermediate field regions with comparable effect. |
