Abstract :
The reversal behavior of the bilayer Au/FePt samples with various thickness of FePt ordered layers is studied. By comparing demagnetizing curve, dc demagnetization curve, initial curve, and isothermal remanent magnetisation curve, different dominated reversal mechanisms are found. The magnetic force microscope images of the films also confirm the domain structures which are related to the different reversal behaviors.
