由于(i)复杂的合成和表征技术的出现以及（ii）高精度理论方法的发展，低维系统中的磁性研究进入了一个新的阶段。我们描述了一种全电子总能量局域自旋密度方法的最新发展和应用，用于确定表面、覆盖层、界面和夹层的结构、电子和磁性能。特别强调，并给出了结果，这些结构涉及过渡金属（V， Cr和Fe），贵金属（Cu， Ag和Au），简单金属（Al）和非磁性过渡金属(W)。由于转换电子穆斯堡尔谱现在允许对理论预测进行详细的逐层测试，因此给出了某些铁体系的超精细磁场。
The study of magnetism in low‐dimensional systems has entered a new phase thanks to (i) the advent of sophisticated synthesis and characterization techniques and (ii) the development of highly precise theoretical methods. We describe recent developments and applications of an all‐electron total energy local spin density approach for determining the structural, electronic, and magnetic properties of surfaces, overlayers and interfaces, and sandwiches. Particular emphasis is placed, and results are given, on these structures involving transition metals (V, Cr, and Fe) on noble metals (Cu, Ag, and Au), simple metals (Al), and a nonmagnetic transition metal (W). Magnetic hyperfine fields are given for some Fe systems since conversion electron Mossbauer spectroscopy now permits detailed layer‐by‐layer tests of the theoretical predictions.
