First order reversal curve diagrams of perpendicular magnetic anisotropy films

Abstract

The exchange coupling and magnetic properties distributions in Co/Pd multilayer perpendicular magnetic anisotropy films with different magnetic properties are investigated using the experimental first order reversal curve (FORC) diagram with assistance of Landau-Lifshitz-Gilbert simulation. The simulated FORC diagrams of perpendicular magnetic anisotropy films with different exchange couplings and magnetic property distributions are quite different, which make FORC diagrams very powerful for characterizing perpendicular magnetic recording media. © 2009 American Institute of Physics.
