摘要
本文应用具有关联有效场理论,研究了一个新的横场半无限Ising系统。该系统由一个超薄磁性膜和一个不同磁性的半无限基构成,界面耦合可以是铁磁的或者是反铁磁的。磁化和相图的数值结果表明了许多有趣的性质。
With the effective-field theory with correlation, we study a system composed of a Ising ultra-thin film and different semi-infinite substrate and the interfacial coupling is ferromagnetic (or antiferromagnetic). The numerical results of the magnetisations and phase diagrams show that some interesting properties.
