Finite-temperature study of a modulation-doped DMS quantum well with broken spin symmetry

We present a finite-temperature self-consistent calculation of the electronic properties in a modulation doped dilute magnetic strucuture (DMS) QW structure with broken spin-symmetry. The spin-split subband structure is calculated at finite temperatures as a function of applied magnetic field. Temperature and magnetic field effects on the electronic properties are analyzed for various degrees of spin polarization. Carrier-induced magnetism and the possible ferromagnetic–paramagnetic phase transitions are analyzed in terms of various material parameters of the DMS QW structures.
