Effect of the orientation of the Fe-3% Si crystal surface with respect to crystallographic axes on the dynamic behavior of the domain structure and magnetic losses in rotating magnetic fields

摘要

A domain structure and its dynamic transformation in a rotating magnetic field are experimentally studied over a wide induction range (up to 1.7 T) on a single-crystal plate whose surface deviates through angle beta from a (110) crystallographic plane. The induction ranges of different dynamic behavior of the domain structure are determined. At an induction below 0.5 T, the magnetization reversal of the plate occurs via a change in the main domain structure. At inductions up to 1.4 T, the main structure undergoes strong dynamic fragmentation. At a higher induction, the magnetization reversal of the sample proceeds via the growth of the closure structure localized at the periphery of the sample in the absence of a magnetic field. The dependences obtained support the early considerations regarding the behavior of magnetic losses.
