Abstract :
CoCr/NiFe double layers were investigated by FMR and VSM. The FMR linewidth of NiFe of the double layer is about twice that of a single NiFe layer. The resonance field is the same in both cases. Using the VSM the coercive field of the CoCr layer of the double layer was obtained. It is approximately equal to the coercivity of a single CoCr layer. The initial susceptibility χi=[dM/dH]M=θof the MH curve of CoCr on top of NiFe however differs from that of a single CoCr layer.
