The magnetic properties of antiferromagnetic Mn 3 ZnN anti-perovskite nanoparticles have been studied using Monte Carlo simulations within the Ising model. The considered Hamiltonian includes the exchange interactions between Mn–Mn and the external magnetic field. The thermal magnetizations and magnetic susceptibilities of Mn 3 ZnN anti-perovskite nanoparticles are computed for different sizes. The Néel temperature is deduced. The exchange interaction between Mn and Mn atoms is obtained. Beyond the coupling value 2 K, the magnetization of system becomes independent of effect temperature. In addition, the variation of magnetizations with external magnetic field and crystal filed are also established for different temperatures. Mn 3 ZnN anti-perovskite nanoparticles exhibits the superparamagnetic behaviour for different temperatures value.
