在这项研究中，我们提出了一种金红石相关材料 LiMoO2，它成为簇磁体，并在冷却时在预成型的钼二聚体上表现出自旋单线态形成。与普通簇磁体不同，尽管形成了分子轨道，但原子 dyz 轨道仍能牢固地存在，从而影响所选材料的磁性。这种具有分子和原子轨道特征的混合簇磁体在孤立的簇上实现了多个独立的自旋，为研究孤立的自旋二聚体物理提供了理想的平台。
In this study, we present a rutile-related material, LiMoO2, that becomes a cluster magnet and exhibits a spin singlet formation on a preformed molybdenum dimer upon cooling. Unlike ordinary cluster magnets, the atomic dyz orbital robustly survives despite the formation of molecular orbitals, thereby affecting the magnetic properties of the selected material. Such hybrid cluster magnets with the characters of molecular and atomic orbitals realize multiple independent spins on an isolated cluster, leading to an ideal platform to study the isolated spin dimers physics.
