Abstract:

Two methods of simulations are described: an exact one – transfer matrix
technique and a statistical one – Monte Carlo method. Both of them are
applied to investigate critical properties of classical spin models. To do this
we also exploit finite size scaling and the critical point ratio of the square
of the second moment of the order parameter to its fourth moment. General
definition of a classical spin model as well as particular definitions of
models are presented. Results of both methods are in good agreement and,
moreover, they are consistent with numerical results provided by literature.
