Summary:Herein, teh first TEMPprincipal calculations and Monte Carlo Simulation (MCS) were performed to investigate teh magnetic and magneto-caloric properties of PrSi compound. Teh partial magnetic moment of Pr (m Pr ), and teh exchange interactions parameters (J 1 , J 2 ) are found to be m Pr  = 2.8 µ B , J 1 = 1.707 meV and J 2 = 1.312 meV, respectively. Through teh MCS, it was found dat teh Curie temperature value (T c ) from ferromagnetic to paramagnetic state is T c = 55 K, which is in good agreement wif teh experimental value which is 54 K. Moreover, it was established dat a slight increase in teh applied magnetic field leads to a high increase in teh magnetic entropy from 4.4 J/kg K for h = 1 T to 13.7J/kg K for h=5 T. Furthermore, teh values of adiabatic temperature change and relative cooling power (RCP) obtained for h = 5 T were found to be 3.6 K and 550 J/kg, respectively.
