Hexagonal Perovskites as Quantum Materials

摘要: Hexagonal oxide perovskites, in contrast to the more familiar allow for face-sharing of metal-oxygen octahedra or trigonal prisms within their structural frameworks. This results dimers, trimers, tetramers, longer fragments chains crystal structures, and consequently much shorter metal-metal distances lower metal-oxygen-metal bond angles than are seen perovskites. The presence can have a dramatic impact on magnetic properties these compounds, dimer-based materials, particular, been subjects many quantum-materials-directed studies materials physics. perovskites contemporary interest due potential geometrical frustration ordering moments orbital occupancies at low temperatures, which is especially relevant significance as quantum materials. As such, several hexagonal identified candidates hosting spin liquid state temperatures. In our view, fertile ground finding new review briefly describes solid chemistry
