摘要：
The magnetic properties of antiferromagnetic HoRh nanomaterials have been studied using Monte Carlo simulations within the Ising model framework. The considered Hamiltonian includes the first nearest neighbor, second and third exchange interactions, and an external magnetic field. The thermal magnetizations and magnetic susceptibilities are computed for a fixed size of the nanomaterial. In addition, the Neel temperature is deduced. The magnetization and magnetic susceptibility versus the exchange interactions are studied for a fixed size of the nanomaterial. The magnetic hysteresis cycle versus temperature is also established.
