Exchange Interactions in La2CuIrO6 Double Perovskite: Monte Carlo Calculation

This theoretical work uses Monte Carlo simulation to calculate exchange interactions in the double perovskite La 2 CuIrO 6 . The numerical method employed in this research is constructed around the Ising model’s correlation between internal energy and magnetism on each site. The experimental transition temperature ( T C exp ) obtained beneath an external magnetic field h of 0.5 T has been considered to examine the exchange interactions, considering a parameter α that we have established. Additionally, each magnetic pattern’s internal energy, as well as magnetization on each site, magnetic susceptibility, and specific heat, has been calculated in this study. The estimated exchange interactions are, J C u - I r = 7.84 m e V , J C u - C u = - 9.71 m e V , and J I r - I r = 0.54 m e V .
