ABSTRACT:
A low-anisotropy magnetic material is exchange coupled in juxtaposition with a compatible body of high-anisotropy magnetic material so that a reduced external magnetic field is required for the nucleation and passage of a domain wall from the low-anisotropy material, through the interface between the low- and high-anisotropy materials, and into the high-anisotropy material. The propagation of the domain wall continues to affect a reversal in the direction of magnetization in the high-anisotropy material.
