Abstract

We use the Hanle effect to study spin relaxation in Zn_xCd _1-xSe epilayers grown on lattice-matched InP substrates. We study three samples with a fixed composition (x = 0.4) and with varying levels of n-doping, as well as an undoped sample with x = 0.5. Our measurements show that the spin relaxation time changes non-monotonically as a function of carrier density, with a maximum transverse spin lifetime of ∼10.5 ns at low temperatures for a sample doped near the metal-insulator transition.
