| 1 | Magnetic properties of La2CuMnO6 double perovskite ceramic investigated by Monte Carlo simulations显示文摘We present a theoretical study of the magnetic properties of the lanthanum copper manganate double perovskite La2CuMnO6 ceramic,using Monte Carlo simulations.We analyze and discuss the ground state phase diagrams in different planes to show the effect of every physical parameter.Based on the Monte Carlo simulations,which combine Metropolis algorithm and Ising model,we explore the thermal behavior of the total magnetization and susceptibility.We also present and discuss the influence of physical parameters such as the external magnetic field,the exchange coupling interactions between magnetic atoms,and the exchange magnetic field on the magnetization of the system.Moreover,the critical temperature of the system is about Tc=70 K,in agreement with the experimental value.Finally,the hysteresis loops of La2CuMnO6 are discussed. | S Mtougui I EL Housni N EL Mekkaoui S Ziti S Idrissi H Labrim R Khalladi L Bahmad | 2020 | Chinese Physics B2020，29，5： | 1 |
