  1. A. Bove, F. Altomare, N. Kundtz, A.M. Chang, Y.J. Cho, X. Liu, and J. Furdyna, Electron-mediated ferromagnetism and small spin-orbit interaction in molecular-beam-epitaxy grown n-type GaAs/Al0.3Ga0.7As heterostructures with Mn δ-doping (2007) .

    We report the first evidence of electron mediated ferromagnetism in a molecular-beam-epitaxy (MBE) grown GaAs/Al0.3Ga0.7As heterostructure with Mn δ-doping. The interaction between the magnetic dopants (Mn) and the 2-dimensional electron gas (2DEG) realizes magnetic ordering when the temperature is below the Curie temperature (TC~3.2K) and the 2DEG is brought in close proximity to the Mn layer by gating.
