MONTE CARLO SIMULATIONS OF A DISORDERED BINARY ISING MODEL

In this work we study a disordered binary Ising model on the square lattice. The model system consists of two different particles with spin-1/2 and spin-1, which are randomly distributed on the lattice. It has been considered only spin nearest-neighbor exchange interactions with
