Magnetic behaviors of a ferrimagnetic decorated kagome-like lattice under an external magnetic field

摘要

The Monte Carlo study has been directed to the magnetic behaviors of a ferrimagnetic decorated kagome-like lattice by establishing the mixed spin-2 and spin-5/2 Ising system. Magnetization, susceptibility, internal energy, specific heat and entropy as a function of temperature have been discussed under the influence of diverse Hamiltonian parameters. The change of the critical temperature and compensation temperature with various parameters is also gained. Interestingly, two compensation points behavior may appear in certain parameter range. In particular, we have found that the present system can display various multiple-loop hysteresis behaviors because of the competition among different Hamiltonian parameters.
