In order to investigate the stable magnetic structure of the Hubbard model on a squre lattice, we utilize the dynamic~ simulated annealing method which proposed by R. Car and M. Parrinello. Results of simulations on a 10 ร I0 lattice system with 80 electrons under assumption of colIinear magnetic st
The critical properties of the d-dimensional Blume-Capel model is studied by using the mean field renormalization group method. The phase diagram and tricritical behaviour of the square lattice and various three-dimensional lattices have been analysed. Results are compared with those of high-tempera
