Abstract Studies of magnetic adatoms on surfaces utilize experimental techniques (scanning tunneling microscopy (STM), inelastic tunneling spectroscopy (ITS) and ab-initio modeling methods. Several fundamental issues involved in these studies, being of utmost importance in view of potential technological applications, are critically examined and elucidated. This includes applications of the correspondence principle and relationships between the notions: magnetic anisotropy (MA), magnetic anisotropy energy (MAE), single-ion anisotropy (SIA), zero-field splitting (ZFS) as well as spin-flip energy of tunneling electrons and energy barrier to magnetization reversal. Proper quantum–mechanical relations between the uniaxial SIA constant K and the axial ZFS parameter D valid for the cases D > 0 and D

对应原理是否会导致表面吸附原子的单轴磁各向异性常数K与轴向零场分裂参数D之间的关系不正确？

摘要 表面磁性吸附原子的研究利用实验技术（扫描隧道显微镜 (STM)、非弹性隧道光谱 (ITS) 和 ab-initio 建模方法。这些研究中涉及的几个基本问​​题，鉴于潜在的技术应用，是最重要的，严格审查和阐明。这包括以下概念之间的对应原理和关系的应用：磁各向异性 (MA)、磁各向异性能量 (MAE)、单离子各向异性 (SIA)、零场分裂 (ZFS) 以及隧道电子的自旋翻转能量和磁化反转的能垒。单轴 SIA 常数 K 和轴向 ZFS 参数 D 之间的正确量子力学关系适用于 D > 0 和 D 的情况
