Abstract
From measurements of the Current-Perpendicular-to-Plane (CPP) resistances and magnetoresistances (MRs) of sputtered [F/Al]N (F= Co, Fe, Co91Fe9) multilayers with N-bilayers, and F/Al-based exchange-biased spin-valves, we estimate interface specific resistances, 2ARFAl/*, and scattering asymmetries, gammaF/Al, for each metal pair at 4.2 K. In all three cases, 2ARFAl/*is large and gammaFAl/is small, comparable to the recently determined values of 2ARPyAl/* ~9fOmegam2and gammaPyAl/~0.03 for Permalloy (Py)/Al interfaces. The values of 2ARF/Al* with Al are too large to be explained by the resistivities of alloyed F/Al interfaces. The similarity of results for Py, Fe, Co, and Co91Fe9suggests that spin dependent scattering at F/Al interfaces is determined mainly by the properties of Al. We find that F/Al interfaces are not stable over time at 295 K or upon annealing to 450 K
