Non-collinear magnetism in the post-perovskite thiocyanate frameworks CsM(NCS)$_3$ [PDF]
arXiv, 2023 AMX$_3$ compounds are structurally diverse, a notable example being the post-perovskite structure which adopts a two-dimensional framework with corner- and edge-sharing octahedra. Few molecular post-perovskites are known and of these, none have reported magnetic structures.
