Leveraging the flexible material designability of organic-inorganic hybrid systems, spatial inversion symmetry breaking and spin-orbit coupling (SOC) were simultaneously controlled in a series of two-dimensional organic-inorganic hybrid perovskite (2D-OIHP) copper halides with ferromagnetic exchange interaction (FMI). In chiral molecule-incorporated 2D-OIHP copper halides, an increase in Br component over Cl component at halogen sites leads to systematic variations in magnetic phase diagrams owing to the competition between the FMI and Dzyaloshinskii-Moriya interaction induced by the SOC. The crucial role of noncentrosymmetry in the competition for the magnetic interactions was confirmed by comparing the magnetic phase diagrams of chiral and achiral 2D-OIHP copper bromides.

具有铁磁交换相互作用的手性分子掺入的二维有机-无机杂化钙钛矿铜卤化物中自旋轨道耦合的调谐

利用有机-无机杂化系统的灵活材料设计能力，在一系列具有铁磁交换相互作用的二维有机-无机杂化钙钛矿（2D-OIHP）卤化铜中同时控制空间反演对称性破缺和自旋轨道耦合（SOC） （FMI）。在手性分子掺入的 2D-OIHP 卤化铜中，由于 SOC 引起的 FMI 和 Dzyaloshinskii-Moriya 相互作用之间的竞争，卤素位点上 Br 组分相对于 Cl 组分的增加导致磁相图的系统变化。通过比较手性和非手性 2D-OIHP 溴化铜的磁相图，证实了非中心对称性在磁相互作用竞争中的关键作用。
