摘要翻译：
首次在恒压系综中用蒙特卡罗模拟了自旋交叉材料的压致相变。在这里，我们采用了不同自旋态，即高自旋态和低自旋态，由于分子尺寸的不同而引起的晶格畸变之间的弹性相互作用作为合作相互作用的起源。我们研究了有序过程的温度依赖性是如何随压力变化的，并且我们得到了一个温度依赖性的标准序列，该序列在改变其他参数如配体场的强度时被发现（S.Miya*****a et al.，prog.theor.phys.\textbf{114}，719(2005))。从统一的观点考察了压强对自旋交叉有序化过程的各种影响。

英文摘要：
Pressure-induced phase transitions of spin-crossover materials were simulated by a Monte Carlo simulation in the constant pressure ensemble for the first time. Here, as the origin of the cooperative interaction, we adopt elastic interaction among the distortions of the lattice due to the difference of the molecular sizes in different spin states, i.e., the high spin (HS) state and the low spin (LS) state. We studied how the temperature dependence of the ordering process changes with the pressure, and we obtained a standard sequence of temperature dependences that has been found in changing other parameters such as strength of the ligand field (S. Miya*****a et al., Prog. Theor. Phys. \textbf{114}, 719 (2005)). Various effects of pressure on the spin-crossover ordering process are examined from a unified point of view.
