Here we study how this affects the spin-subband populations and the spin-polarization as functions of the temperature, T, and the in-plane magnetic field, B, for narrow to wide dilute-magnetic-semiconductor quantum wells. We examine a wide range of material and structural parameters, focusing on the quantum well width, the magnitude of the spin-spin exchange interaction, and the sheet carrier concentration. Generally, increasing T, the carrier spin-splitting, Uoσ, decreases, augmenting the influence of the {\textquotedblleft}minority{\textquotedblright}-spin carriers. Increasing B, Uoσ, increases and, accordingly, carriers populate {\textquotedblleft}majority{\textquotedblright}-spin subbands while they abandon {\textquotedblleft}minority{\textquotedblright}-spin subbands. Furthermore, in line with the density of states modification, all energetically higher subbands become gradually depopulated. We also indicate the ranges where the system is completely spin-polarized.}, doi = {10.1103/PhysRevB.75.195344}, url = {https://journals.aps.org/prb/abstract/10.1103/PhysRevB.75.195344}, author = {Simserides, C.} }
