Good Agreement

We present a simple theoretical description of recently measured giant magnetoresistance (GMR) effect in granular ferromagnetic systems. We propose that single-domain ferromagnetic particles embedded in a metallic medium form a series of randomly distributed and spin-dependent potential barriers and wells. This spin-dependent scattering is considered as the main origin of the GMR effect. Good agreement with experiment is found for phase-separated Co x Cu 1−x samples.
