Abstract
By utilizing the Monte Carlo simulation , how different physical parameters affect the dynamic magnetic properties and magnetocaloric effects of a Kagome-like cluster with mixed spins (3/2, 2) are explored. The findings show that changing the values of the exchange coupling | J |, | J s |, and | J 2 | had no impact on the saturation order parameters of the system. Under specific parameter conditions, the magnetization susceptibility curve displays double peaks, and compensation phenomena are noted. The impacts of h bias and h osc on the blocking temperature of the system are opposite. In addition, the effects of various parameters on the magnetization, magnetic entropy change , and relative cooling power of the ferromagnetic system under a static magnetic field are given. The strong exchange coupling is found to negatively affect the magnetic refrigeration efficiency of the material, while a strong magnetic field enhances the system's relative cooling power.
