Damping of Manganese Spin Precession in the Presence of Free Carriers in CdMnTe Quantum Wells

Abstract

The transverse relaxation time T2 of the Mn spins has been measured by time resolved photo induced Kerr rotation in n-type and p-type CdMnTe quantum wells with a magnetic field applied parallel to the quantum well plane. The dependencies of T2 on the magnetic field and on the carrier density indicate the influence of carriers on T2. A model, akin to dielectric relaxation, is proposed to explain qualitatively these results.
