Electron paramagnetic resonance of Mn2+ in strained-layer semiconductor superlattices

Abstract

We report giant crystal field splittings of Mn2+ electron paramagnetic resonance (EPR) lines observed in ZnTeMnTe and ,nu>CdTeMnTe superlattices. The EPR spectra of isolated Mn2+ ions diffused into the ZnTe or the CdTe layers provide a direct and precise measure of both the magnitude and the uniformity of strain produced by lattice mismatch between the superlattice constituents.
