摘要
The EffectiveField Theory with correlations (EFT) based on the probability distribution is used to investigate the magnetic hysteresis behaviors of both hexagonal and square 2D nanoparticles consisting of a ferromagnetic spin-1/2 core and a ferromagnetic spin-1 shell. The system parameters such as the ferrimagnetic exchange core/shell interaction, the surface shell exchange coupling and the reduced temperatureare examined on the magnetic hysteresis behaviors. Some interesting results have been found such as multiple hysteresis loop behaviors.
