Electron paramagnetic resonance in ac dissipation was observed due to the Cooper pairs breaking up to their quasiparticle state. This phenomenon is the result of a flux motion on a pinning centers in high temperature superconducting materials. The detection of ac dissipation was performed in a low ac field (15 and 22 MHz) as well as in microwave range. Vortex motion hysteresis loop with magnetic field modulation of 15 Hz was recorded. Besides V-shaped dependence of ac power dissipation P(B), a direct electron paramagnetic resonance signal related to Cooper pairs → quasiparticle fluctuation was observed.
