Abstract :
The possibility of increasing the DW (domain wall) velocity in high-Bi-content films was assessed experimentally. Bi-Pr-Lu-substituted garnet films with a GGG-CaMgZr substrate (210) which show very high DW velocities for a relatively low driving field and a high magnetooptical parameter were obtained. In these films, rhombic anisotropy is chiefly of the growth type, and variations of magnetic properties with temperature make these films promising media in fast magnetooptical devices
