Abstract

We have used time-resolved Kerr rotation to investigate carrier spin relaxation in bulk InP:Fe from 80K to room temperature. We observe several coexisting mechanisms contributing to spin relaxation with different time scales, as well as a rich but intricate dependence on the illumination frequency and intensity. In particular, we find indications of strong many-body interactions that result in a slower relaxation rate with increasing excitation intensity and that, possibly, generate spin level splitting in the absence of magnetic fields.
