Vv. Ustinov et Ea. Kravtsov, CORRELATION BETWEEN GIANT MAGNETORESISTANCE AND MAGNETIZATION IN METALLIC SUPERLATTICES - A COMPARISON OF PERPENDICULAR AND INPLANE GEOMETRIES, Journal of magnetism and magnetic materials, 148(1-2), 1995, pp. 307-308
The problem of perpendicular and in-plane spin-dependent transport in
magnetic superlattices is treated within a unified semi-classical appr
oach. By starting from the Boltzmann equation with exact boundary cond
itions, we calculate the magnetoresistance in both geometries. A corre
lation between the giant magnetoresistance and the superlattice magnet
ization is also considered.
