Abstract

We report on a first-principles study of Sr₂CoO₂Cl₂ which contains CoO₂ square planes separated by SrCl layers.Our results reveal that its striking behavior relies on the occupation of the 3d d_xz/d_yz orbitals of high-spin Co. Such an electronic state avoids Jahn–Teller effects, which cause electrostatic and hybridization effects. Therefore, it is easier to distinguish the shift of orbital arrangement with the variation of the Co-Cl distance and the Co-O distance.
