Abstract
The domain wall (DW) coercive field, H-cw, can be considerably reduced if DWs are in a high local magnetic field gradient, G. In experiments G was varied between 10(9) and 10(10) A/m(2) by changing the size of domains in magnetic garnet films, which reduced H-cw by factors of 4-9. These data were compared with a model calculation of H-cw(G) due to hysteresis losses of a DW moving in a stochastic pinning field profile.
