Novel state of matter in the site-ordered double perovskites Ba2YWO6

In solids, spins and orbitals are usually not coupled to each other. This may be not true any more in the rocksalt ordered double perovskites having spin-orbit coupling....在固体体系中，自旋（spin）与轨道（orbital）通常并不发生相互耦合。但对于具备自旋轨道耦合（spin-orbit coupling）的岩盐型有序双钙钛矿（rocksalt ordered double perovskites）而言，这一结论或许不再成立。
