Abstract:
A two-dimensional spin-pseudospin model is considered, which generalizes a diluted antiferromagnetic Ising model with charged nonmagnetic impurities in the case of two types of charges. The analytical results in the Bethe approximation are compared with the results of numerical simulation using the classical Monte Carlo method for various parameters.
The work was supported by Program 211 of the Government of the Russian Federation, agreement 02.A03.21.0006, projects nos. 2277 and 5719 of the Ministry of Education and Science of the Russian Federation, and Russian Foundation for Basic Research (project 18-32-00837_18).
