摘要：
The dynamic magnetic and thermodynamic behaviors of the mixed-spin (1/2, 1, 3/2) Ising edge-modified graphene-like nanoparticles in a time-dependent magnetic field are studied by Monte Carlo simulation. The influence of temperature, exchange coupling, crystal field, and time-dependent magnetic field on the dynamic order parameter, magnetic susceptibility, and internal energy are investigated. The simulations reveal that the compensation behavior of the system occurs in a certain parameter range. Strong crystal field and weak exchange coupling promote the compensation behavior in the system, while increasing the amplitude of the oscillating magnetic field reduces the compensation temperature. Furthermore, the system shows the interesting multiple dynamic hysteresis behaviors under the influence of different parameters.
