During 2001 year, the methods of magnetoresistive and magnetooptical measurements of thin films were improved and studies of ultrathin (up to 10 nm) ferromagnet - non-magnetic metal - ferromagnet trilayers were performed. Two peaks corresponding to antiferromagnetic ordering in the system have been observed on the dependence of magnetoresistance vs spacer thickness. A new theoretical approach has been developed, which is based on employing the general quantum mechanical transmission coefficient for electron Bloch waves with an arbitrary dispersion law. Numerical calculations and theoretical analysis of the spin-dependent tunneling of electrons through a thin insulating spacer have been performed in the ballistic regime.
