Микромагнитное моделирование периодических цепочек переходных структур в вихревых доменных стенках (параллельные вычисления в среде МuМах 3)

Abstract

Many properties of magnetically ordered materials depend on existence and dynamical behavior o f locally inhomogeneous transition structures (TS’s) in domain walls (DW’s). This work deals with TS’s, which emerge in asymmetric Bloch domain walls and their chains’ interaction. We achieve energies of domain walls as functions o f the distance between two TS’s in presence and absence of external field in order to determine the kind of interaction: repulsion, attraction or fixing on definite distance. We have adapted the OOMMF programs for the parallel processing package MuMAX 3.
