Ferromagnetic resonance (FMR) of glass-coated amorphous Fe78Ni8P10B10 and Co67Fe4Cr7Si8B14 microwires was investigated at frequency 9.54 GHz by the standard FMR and the electrically detected FMR techniques. Static magnetic field was applied parallel to the wire axis and the resonance was driven by the microwave current passing through the wire. The field dependences of electrical resistance measured at different levels of microwave power were compared with the resonance curves obtained by the standard FMR method. It was found that the change of resistance observed at the resonance is caused by the increase of temperature due to the energy dissipation by the Gilbert damping of spin-precession motion.
