Spin clustering and ferromagnetic couplings in a dilute magnetic semiconductor
Avinash Singh
Ferromagnetic couplings in spin clusters are shown to be strongly enhanced compared to those for an ordered impurity arrangement, even for the same spin separation and hole doping.…

Ferromagnetism in a dilute magnetic semiconductor -- Generalized RKKY interaction and spin-wave excitations
Avinash Singh, Animesh Datta, Subrat K. Das +1
Carrier-mediated ferromagnetism in a dilute magnetic semiconductor has been studied using i) a single-impurity based generalized RKKY approach which goes beyond linear response the…
