Abstract


Evolution of magnetic interaction has been investigated in Co/Pd multilayer films with 5, 9 and 15 repeats. All these samples were characterized by Isothermal remanence magnetization (IRM), DC demagnetization (DCD) and first order reversal curve (FORC). The δM plots obtained from the IRM and DCD data indicate exchanging coupling evolves into magnetostatic interaction as the repeat increases from 5 to 15. The FORC measurement was used to confirm this evolution and the FORC diagrams exhibit the effect of magnetic interaction on the reversal mechanism.
