Electron spin coherence in long wavelength Hg/sub 1-x/Cd/sub x/Te

The authors have used the Dutch free electron laser (FELIX) to measure spin coherence times in long wavelength Hg/sub 1-x/Cd/sub x/Te at wavelengths between 4 and 10 /spl mu/m and from 4-300K. In particular, they measure remarkably long spin coherence times at 300K.
