摘要：

We study novel transport properties in metallic magnetic multilayers, to elucidate whether they can explain the giant magnetoresistance effect observed in those systems. Realistic Fermi surface topologies in layered ferromagnets are taken into account, with the possibilities of different types of orbits depending on the electron spin. Scattering from the spacer couples orbits of different topologies at both sides of the interface in a way similar to magnetic breakdown phenomena, with new interesting effects for the transport properties of multilayers.
