Abstract ： In a free-electron approximation, transport properties of magnetic tunnel junctions with nonmagnetic metallic spacers and cap layers were studied. The magnetoresistance is oscillatory functions of the thicknesses of non-magnetic metallic spacers and ferromagnets, their period is determined by the Fermi surface properties of the metals, and magnetoresistances (up to about 103 %) much greater than those predicted by the Julliere's model are obtained. The results indicate that this structure has potential in designing spin-polarized tunneling devices.
