Abstract

ABSTRACT Using the Monte Carlo method, the ferrimagnetic mixed-spin (3/2, 5/2) Ising model is proposed to research the physical properties of graphene cluster monolayer, such as magnetization, susceptibility, internal energy, specific heat and hysteresis loops. The phase diagrams are also gained to investigate the blocking temperature TB and the discontinuous point TK under the different parameters. The abundant multi-loop hysteresis characteristics are observed, such as quintuple-loop, triple-loop and double-loop, owing to the competition among various parameters.

各向异性对石墨烯簇单层磁性和热力学性质的影响

摘要利用蒙特卡罗方法，提出了铁磁混合自旋（3/2，5/2）Ising模型，研究了石墨烯团簇单层的物理性质，如磁化强度、磁化率、内能、比热和磁滞回线。还获得了不同参数下的阻塞温度TB和不连续点TK的相图。由于各种参数之间的竞争，观察到丰富的多回路磁滞特性，如五回路、三回路和双环。

期刊介绍： Phase Transitions is the only journal devoted exclusively to this important subject. It provides a focus for papers on most aspects of phase transitions in condensed matter. Although emphasis is placed primarily on experimental work, theoretical papers are welcome if they have some bearing on experimental results. The areas of interest include: -structural phase transitions (ferroelectric, ferroelastic, multiferroic, order-disorder, Jahn-Teller, etc.) under a range of external parameters (temperature, pressure, strain, electric/magnetic fields, etc.) -geophysical phase transitions -metal-insulator phase transitions -superconducting and superfluid transitions -magnetic phase transitions -critical phenomena and physical properties at phase transitions -liquid crystals -technological applications of phase transitions -quantum phase transitions Phase Transitions publishes both research papers and invited articles devoted to special topics. Major review papers are particularly welcome. A further emphasis of the journal is the publication of a selected number of small workshops, which are at the forefront of their field.
