Abstract

We observed a new type of hysteresis in cyclotron resonance spectra of two-dimensional electron gas confined in GaAs/AlGaAs multi quantum wells when we applied high magnetic fields tilted from the growth direction. Pulsed high magnetic fields up to 150 T were generated by the single turn coil technique. We investigated in detail the condition for the occurrence of the hysteresis which is a disagreement between two traces in the up- and down-sweeps of the pulsed magnetic fields. The dependencies of the hysteresis on the wavelength, sweep rate of the fields and temperature has led to the conclusion that the hysteresis is due to inequilibrium states in the up-sweep of tilted magnetic fields. The relaxation time from inequilibrium to equilibrium states was revealed to be of the order of microsecond.
