Abstract:
The temperature dependence of microwave absorption minima observed at cyclotron resonance harmonics in a two-dimensional electron system implemented in a GaAs/AlGaAs heterostructure has been studied. The coexistence of this effect with the temperature-dependent giant negative magnetoresistance has been revealed. A possible explanation of the results by the effect of electron-electron scattering on the non-Markovian electron kinetics has been discussed.
