Abstract :
For amplitude asymmetry control and thermal stability control at higher areal density, synthetic spin valve is one of the key technologies. We developed a micromagnetics model for synthetic SV with semi-classical GMR theory and estimated optimum set of thicknesses of synthetic pinned layers. The ratio of two pinned layer thicknesses is around 1.5~1.8 for good asymmetry and high ESD resistance
