-Four NiFe/Co/Cu/Co/NiFe/MnNi spin valves (SVs) with two different growth configurations have been investigated by conventional and high resolution electron microscopy (CTEM and HREM). Structures with the MnNi pinning layer above and below the ferromagnetic sandwich in both as-grown and annealed states have been studied. A correlation between their magnetic properties and their microstructure has been found. For each of these configurations, the structure of the MnNi pinning film is different and as a result, the exchange field (Hex) value changes. In addition, the coercivity (Hc) of the sense layer seems to be related to its grain size and cristallographie texture.
