|Title:||Non-collinear spin transfer in Co/Cu/Co multilayers|
|Published:||May 15, 2002|
|Abstract:||We report semi-classical calculations of current polarization, spin accumulation, magnetoresistance, and spin transfer torques in Co/Cu/Co multilayers. A 2 x 2 matrix Boltzman equation is used because the Co layer magnetizations are not necessarily parallel. Spin-flip scattering induces current polarization in these structures and, by incorporating spin-transfer mechanisms proposed by Slonczewski and Berger, we study the torques exerted on the Co layers by the conduction electrons. Quantitative comparison with relevant experiments yields mixed results.|
