Abstract
Synthetic top and bottom spin valves including the Mn-Ir-Pt/Co-Fe (P1)/Ru/Co - Fe (P2) synthetic pinned layer were prepared by controlling the thickness difference (Δt = P1 - P2) of Co-Fe layers. The effective exchange field (Heff,ex) and giant magnetoresistance (GMR) properties of both synthetic type SVs were investigated as a function of Δt. The Heff,ex was dependent largely on the Δt. The GMR properties are strongly dependent on the stacking sequence of synthetic SVs and Δt. Based on the magnetic and electrical properties at room temperature, the thermal stability of synthetic SVs was also evaluated at various elevated temperatures in both types of SVs.
