Abstract
We report a striking in-plane anisotropy of the spin-flip Raman signals observed for dilute magnetic Cd${}_{1\ensuremath{-}x}$Mn${}_{x}$Te quantum wells containing a two-dimensional electron gas. The effect depends upon electron concentration, which can be varied within a single sample via secondary above-barrier illumination. The experimental results are described in a simple, single-electron picture by a model of the conduction band Hamiltonian that includes contributions from Dresselhaus, Rashba, and Zeeman terms.
