Ferromagnetism in Dilute Magnetic Semiconductors
R. da Silva Neves, A. Ferreira da Silva, R. Kishore
We study the ferromagnetism of Ga1-xMnxAs by using a model Hamiltonian, based on an impurity band and the anti-ferromagnetic exchange interaction between the spins of Mn atoms and…

Thermodynamics of infinite U Hubbard model
R. Kishore, A. K. Mishra
The infinite U Hubbard model, with exclusion of double occupancy of sites, can be considered as a free orthofermion Hamiltonian which is exactly soluble. It is found that the ortho…
