Resum: The reversal mechanisms of graded anisotropy FePtCu films have been investigated by alternating gradient magnetometer AGM and magneto-optical Kerr effect MOKE measurements with first-order reversal curve FORC techniques. The AGM-FORC analysis, which clearly shows the presence of soft and hard components, is unable to resolve how these phases are distributed throughout the film thickness. MOKE-FORC measurements, which preferentially probe the surface of the film, reveal that the soft components are indeed located toward the top surface. Combining AGM-FORC with the inherent surface sensitivity of MOKE-FORC analysis allows for a comprehensive analysis of heterogeneous systems such as graded materials.
