Abstract

The domain wall (DW) coercive field, Hcw, can be considerably reduced if DWs are in a high local magnetic field gradient, G. In experiments G was varied between 109 and 1010 A/m2 by changing the size of domains in magnetic garnet films, which reduced Hcw by factors of 4-9. These data were compared with a model calculation of Hcw(G) due to hysteresis losses of a DW moving in a stochastic pinning field profile.
