We consider a two-dimentional spin-pseudospin model to study the critical properties of a diluted Ising magnet. The model with charged impurities is frustrated due to competition between charge and spin orders. We used classical Monte Carlo method to obtain the ground state phase diagram, and study unconventional phase states at finite temperatures, including order-order and reentrant phase transitions.
