Abstract
We present a current-conserving method to calculate the current-perpendicul ar-to-plane conductivity using Kubo's formula in magnetic superlattices. We use this method to study the interface scattering in Co/Cu (111) superlatt ices with different sources of scattering: clean interfaces with Fermi surf ace mismatch, spin-independent, and spin-dependent impurities. We find sign ificant changes to the density-of-states under moderate impurity scattering . (C) 1999 American Institute of Physics. [S0021-8979(99)78108-9].
