  • Abstract
    The spin-dependent electron scattering in multilayer films consisting of Cu and two magnetic materials, Co and Ni80Fe20 alloy, was investigated. In the magnetization process, a giant ferrimagnetic state is realized at moderate external field because of the difference in coercive forces. When the magnetizations of two ferromagnetic layers are antiparallel to each other, the electrical resistivity increases due to spin-dependent electron scattering. The MR ratio was observed to be 10% at room temperature and 28% at 80K in the multilayers film [Ni80Fe20 (25Å) /Cu (55Å)/Co (25å)/Cu (55Å)]×l5 film.
