摘要
蒙特卡洛模拟被用来研究由两个区块组成的多层系统的临界行为：上层区块 A 具有自旋-5/2，下层区块 B 具有自旋-3/2。首先研究了层数的影响，以确定选择的最佳层数。在特定参数下，推导了交换耦合和晶体场常数对总磁化和亚晶格磁化、电感和内能的影响。还建立了不同参数影响下的相图。此外，我们还分析了温度、交换耦合作用和晶体场选定值下的磁滞周期。最后，我们注意到，我们的研究结果与其他人的理论和实验研究结果具有可比性。
Monte Carlo simulation of the magnetic properties of a multilayer mixed-spin system (5/2, 3/2)
A Monte Carlo simulation has been employed to investigate the critical behavior of a multilayer system composed of two blocks: the upper block A with spin-5/2 and the bottom one B with spin-3/2. In the first instance, the effect of number of layers is studied in order to determine the optimal number of layers to select. The influence of exchange coupling and crystal fields constants on total and sublattice magnetizations, susceptibilities, and internal energy is deduced for specific parameters. The phase diagrams under the effect of different parameters have also been established. Moreover, We analyzed the hysteresis cycles for selected values of temperature, exchange coupling interaction and the crystal fields. At last, we noticed that our findings are comparable with the results of theoretical and experimental studies carried out by others.
期刊介绍：
Vacuum is an international rapid publications journal with a focus on short communication. All papers are peer-reviewed, with the review process for short communication geared towards very fast turnaround times. The journal also published full research papers, thematic issues and selected papers from leading conferences.
A report in Vacuum should represent a major advance in an area that involves a controlled environment at pressures of one atmosphere or below.
The scope of the journal includes:
1. Vacuum; original developments in vacuum pumping and instrumentation, vacuum measurement, vacuum gas dynamics, gas-surface interactions, surface treatment for UHV applications and low outgassing, vacuum melting, sintering, and vacuum metrology. Technology and solutions for large-scale facilities (e.g., particle accelerators and fusion devices). New instrumentation ( e.g., detectors and electron microscopes).
2. Plasma science; advances in PVD, CVD, plasma-assisted CVD, ion sources, deposition processes and analysis.
3. Surface science; surface engineering, surface chemistry, surface analysis, crystal growth, ion-surface interactions and etching, nanometer-scale processing, surface modification.
4. Materials science; novel functional or structural materials. Metals, ceramics, and polymers. Experiments, simulations, and modelling for understanding structure-property relationships. Thin films and coatings. Nanostructures and ion implantation.
