Abstract :
In this paper, the antiferromagnetic (AF) NiMn exchange coupled-CoFe films exhibit excellent soft magnetic behaviors with very strong anisotropy at 90deg of the pinning direction is discussed. This led to very high ferromagnetic resonance frequency (FMR) up to 10 GHz with high permeability. These antiferromagnetic exchange coupled multilayers offer new and promising issues for magnetic microwave applications.
