The microwave permeability in a soft magnetic FeCoB film as a function of the external magnetic field is measured in the frequency range from 0.2 to 8 GHz. When the field applied parallel to the orientation of the magnetization varies from 90 to -90 Oe, the permeability spectrum shows hysteretic behavior. Double magnetic resonance peaks come forth and(More)
