TL;DR: In this paper, the dominant effects that control the character of magnetic ordering and the magnitude of carrier-mediated ferromagnetic interactions in various dimensionality structures of diluted magnetic semiconductors are discussed.

TL;DR: In this article, low-temperature magnetotransport measurements (50 mK < T < 4.2 K) on Sb-doped short period SiSiGe superlattices were presented.

TL;DR: In this article, the magnetic-field-induced transfer of electrons into the ground-state subband is discussed in terms of two possible mechanisms: one is the magnetic field induced transfer of the ground state subband, which is charcterized by efficient scattering of electrons by grain boundary defects; the other is magnetic field-induced localization of the two-dimensional electron gas at the grain boundary.

TL;DR: A short overview of recent advances in the field of carrier-controlled ferromagnetism in Mn-based III-V and II-VI diluted magnetic semiconductors and their nanostructures is given in this paper.

TL;DR: In this paper, the authors review studies of excitonic magneto-reflectivity performed on (Ga, Fe)N epilayers, and show how hybridization between d levels and band states, particularly strong in nitrides and oxides, renormalizes the exchange splitting of the valence band states.
