ABSTRACT:
Amorphous ferrimagnetic layers are described with support stable and mobile magnetic charged walls. These layers can be used as drive layers in magnetic bubble domain devices, and are characterized by very weak even-fold in-plane anisotropy, or substantially zero in-plane anisotropy. The layers are metallic alloy compositions having magnetic properties that can be tailored over wide ranges, and are particularly suitable as drive layers for the propagation of bubble domains of extremely small diameters.
