Abstract

We report on magnetospectroscopy investigations on HgSe in the infrared wavelength range using very high pulsed magnetic fields. We have observed interband transitions as well as the cyclotron resonance (CR) of quasi free electrons. Transient effects in the resonance intensities are due to hysteresis effects in the spin dependent population and provide a novel tool for the determination of the spin-lattice relaxation time.
