N2 - Imaginary part of permeability becomes greater than real part in a special case of ferromagnetic resonance in thin films. The distribution of current density in the film arises a phase rotation with huge magnitude to the normal direction of the film. We confirm this phenomenon by experiments, and the application to the high-frequency carrier-type magnetic field sensor makes a remarkable improvement of sensitivity.
