Abstract

Magnetoresistive elements according to this invention comprise magnetically soft material in close proximity to the magnetoresistive material, exemplarily a perovskite manganite. The combination results in magnetic field "amplification", with large resistance changes attainable at relatively low applied fields. The invention exemplarily is embodied in magnetic sensors, e.g., magnetoresistive read/write heads.
