Abstract: A micromagnetic bilayer model, based on the Landau-Lifshitz-Bloch equation, was utilized to study the magnetic, reversal, and spin transport properties of MgO/L10-FePt/Ag/L10-FePt pseudo spin valves. The model simulates a granular bilayer FePt structure and the effects of the Ag spacer were controlled by varying the interlayer exchange strength. Simulation results showed that the reversal of the FePt layers proceeded via reversed domain formation and propagation. Stray fields emanating from the top soft FePt layer reduced the nucleation field of the bottom FePt locally, resulting in the preferential formation of reversed domains at adjacent sites of the bottom hard FePt layer. © 2011 American Institute of Physics.
