The ground states phase diagrams and magnetizations properties of ferrimagnetic model on decorated hexagonal nanolattice have been studied via Monte Carlo simulations. The shape of the phase diagrams depends of the values of the magnetic parameters given in the Hamiltonian. The phase diagrams show some key features: coexistence between regions, points where two, three, four and five and states can coexist. This richness of the ground state phase diagrams can serve as a guide for exploring interesting regions of the model’s finite temperature phase diagrams. The transition temperatures have been deduced for different values of exchange interactions between the atoms of spins moments(S). The effect of crystal field and exchange interactions on magnetization has been investigated. The magnetic coercive field and remanent magnetization are obtained for different parameters such as: exchange couplings and temperatures values. The superparamagnetic behavior has been found at the transition temperature.

装饰六角形纳米晶格上亚铁磁性模型的基态相图和磁化性质:蒙特卡洛研究

通过蒙特卡洛模拟研究了装饰六边形纳米晶格上亚铁磁性模型的基态相图和磁化性质。相图的形状取决于哈密顿量中给出的磁参数值。相图显示了一些关键特征:区域之间共存,两个,三个,四个和五个与状态可以共存的点。基态相图的丰富性可以作为探索模型有限温度相图有趣区域的指南。对于自旋矩(S)原子之间交换相互作用的不同值,已经推导出了转变温度。已经研究了晶体场和交换相互作用对磁化的影响。对于不同的参数(例如:交换耦合和温度值),可以获得矫顽磁场和剩余磁化强度。在转变温度下发现了超顺磁行为。
