|Title:||Experimental separability of channeling giant magnetoresistance in Co/Cu/Co|
|Published:||July 13, 2006|
|Abstract:||The magnitude of the electronic channeling contribution is a significant open issue in the understanding of giant magnetoresistance (GMR). We show that for the technologically important system Co/Cu/Co, channeling GMR can be isolatedand quantified experimentally through measurements in the limit of rapid surface diffuse scattering. First-principles based Boltzmann transport calculation are compared with experimental in-situ magnetoconductance data, which support the possibility of a significant contribution from channeling. Cyclic control of atomic-scale surface roughness, applied during in-situ measurement, will enable a quantitative estimate of the channeling contribution.|
