We have investigated the thermal degradation of spin valve multilayers caused by annealing at 250–300 °C, and determined that it significantly depended on selection of antiferromagnetic layers. Spin valves with a CuAu-I type ordered PtMn antiferro

Linearity of the magnetoresistive (MR) transfer curve for an unshielded spin-valve (SV) sensor was studied. When the NiFe free layer thickness is greater than 5.0 nm, the anisotropic magnetoresistive (AMR) effect in it may overlap the giant magnetore

The relation between giant magnetoresistance (GMR) and the substrate temperature was investigated in sputtered Co/Cu multilayers. The magnetoresistance (MR) ratio is increased as the substrate temperature is decreased. The increase in the MR ratio is
