摘要

在我们的模拟中，我们考虑了两种典型的磁性材料，而第一个包括3d过渡金属，例如钴，它负责在焦绿石结构Rb3CoCl5中存在磁性。第二种磁性材料选择含有4f稀土金属，即镝，它能在石榴石材料Dy3Al5O12中产生磁性。我们的结果与前人的工作基本一致。在我们的计算中，我们对上述现实材料采用了经典的Ising模型。我们专门研究了在一定温度范围内的磁性，包括临界温度和高于临界温度。为了理解磁相变，在经典的Ising模型中加入了磁场的影响。

Monte Carlo Modelling of Magnetic and Thermodynamic Features of Rb3CoCl5 and Dy3Al5O12 Magnetic Systems

In our simulations, we considered two typical magnetic materials, while the first one includes the 3d-transition metal, such as cobalt which is responsible of the presence of magnetism in pyrochlore structure Rb3CoCl5. The second magnetic material was chosen to have 4f-rare earth metal, namely dysprosium that can induce magnetism in garnet material Dy3Al5O12. A general agreement was found between our results and the previous works. In our calculations, we employed the classical Ising model for the above mentioned realistic materials. We specifically studied the magnetic properties over a range of temperature including the critical temperature and above it. To understand the magnetic phase transition, the effect of magnetic field was involved in the classical Ising model.
