摘要翻译:
自由能泛函的二阶泰勒级数展开给出了磁流体的自由能和磁化强度与磁场的依赖关系的解析表达式,这里用偶极Yukawa相互作用势建模。在平均球面近似框架内研究了相应的硬核偶极Yukawa参考流体。我们对磁性和相平衡性质的发现与以前发表的和新的蒙特卡罗模拟数据是定量一致的。

英文摘要:
A second-order Taylor series expansion of the free energy functional provides analytical expressions for the magnetic field dependence of the free energy and of the magnetization of ferrofluids, here modelled by dipolar Yukawa interaction potentials. The corresponding hard core dipolar Yukawa reference fluid is studied within the framework of the mean spherical approximation. Our findings for the magnetic and phase equilibrium properties are in quantitative agreement with previously published and new Monte Carlo simulation data.
