Abstract

The ground state magnetic properties of two dimensional spin-1/2 Falicov-Kimball model on a triangular lattice are studied using numerical diagonalization with Monte Carlo simulation techniques. In the ground state we observe large range magnetic ordered phases like anti-ferromagnetic and ferromagnetic depending on different values of parameters of onsite Coulomb repulsion U and exchange correlation J. The variation of the magnetization of d- and f-electron with J is also studied.
