Modeling of magnetic and magnetocaloric properties of La₀̣.₇Ba₀.₃MnO₃ manganites by Monte Carlo method
In the work the temperature dependence of magnetization, entropy changes, and the Curie temperature of La₀̣.₇Ba₀.₃MnO₃ using Monte Carlo method and Heisenberg model were investigated. We used the magnetic exchange parameters from the first-principles calculations. In the simulation, magnetic Mn³ᐩ an...
