Abstract: | The magnetic properties of a mixed spin-2 and spin-1/2 ferromagnetic diamond chain are studied by effective-field theory and Monte Carlo (MC) simulation based on Ising model. The temperature dependences of magnetization, magnetic susceptibility, internal energy, and specific heat are studied, respectively. The exchange interaction dependences of magnetization and the critical temperature are calculated by MC simulation. The changes of magnetization depend on field increasing and then field decreasing under steady-static conditions are also given. |
