The Critical Properties of Anisontropic Ising Model with Competing Interactions in the Region of Transition from Modulated Phase into Paramagnetic

Abstract

The anisotropic Ising model with competing interactions in the region of transition from a modulated phase into paramagnetic state is investigated by the Monte-Carlo methods. By means of histogram analysis and the finite-size scaling method, the modulated - paramagnetic phase transition is shown to be a second order phase transition. Critical parameters and temperatures of phase transitions in this region are calculated.
