Itinerant ferromagnetism in a spin-fermion model for diluted spin systems
Sourav Chakraborty, Sandip Halder, Kalpataru Pradhan
We investigate the itinerant ferromagnetism using a diluted spin-fermion model, derived from a repulsive Hubbard model, where itinerant fermions are coupled antiferromagnetically t…

Impact of Next-Nearest-Neighbor hopping on Ferromagnetism in Diluted Magnetic Semiconductors
Sourav Chakraborty, Subrat K Das, Kalpataru Pradhan
Being a wide band gap system GaMnN attracted considerable interest after the discovery of highest reported ferromagnetic transition temperature 940 K among all diluted…
