Magnetic properties of double perovskite Sr2RuHoO6: Monte Carlo Simulation

• Sr2RuHoO6 has been studied using Mean-Field Approximation and Monte Carlo.
• Ground state and phase diagrams have been studied.
• The values of the critical exponents are close to the 3D Ising model ones.

In this paper, we have studied the double perovskite complex Sr2RuHoO6 (SRHO) using the Mean-Field Approximation (MFA) and Monte Carlo Simulation (MCS). Firstly, we study the ground state of the phase diagrams depending on the exchange couplings and the crystal fields, on the other hand the magnetic properties has been studied. The obtained results by MFA were compared with those obtained using a MCS. Secondly, we have presented the results for finite sizes analysis, of the magnetization and the susceptibility as a function of reduced temperature. Finally, we obtain the critical reduced temperature and critical values of the exponents υ=0.602±0.011υ=0.602±0.011, γ=1.179±0.022γ=1.179±0.022 and β=0.296±0.018β=0.296±0.018 which these values are nearest to that of 3D Ising model (υ=0⋅632υ=0⋅632, γ=1⋅23γ=1⋅23 and β=0⋅325β=0⋅325 ).
