Monte Carlo Study of Ferroelectric Properties of Tetragonal Tungsten Bronze Compounds

摘要

The multi-component Ising-like network model on x-y rectangular lattice was developed to describe the ferroelectric phase transition in Tetragonal Tungsten Bronze (TTB) com-pounds. Using Monte Carlo simulation with Metropolis algorithm we reproduced thephase diagram of this model as a function of the temperature and exchange interactionand demonstrated it coherence with experimental data.
