Title: Heat dissipation due to ferromagnetic resonance in a ferromagnetic metal monitored by electrical resistance measurement

The heat dissipation due to the resonant precessional motion of the magnetization in a ferromagnetic metal has been investigated. We demonstrated that the temperature during the ferromagnetic resonance can be simply detected by the electrical resistance measurement of the Cu strip line in contact with the ferromagnetic metal. The temperature change of the Cu strip due to the ferromagnetic resonance was found to exceed 10‚ÄČK, which significantly affects the spin-current transport. The influence of the thermal conductivity of the substrate on the heating was also investigated.
