Antiferro octupolar order in the 5d^{1} double perovskite Sr_{2}MgReO_{6} and its spectroscopic signatures
“Hidden”-order phases with high-rank multipolar order parameters have been recently detected in several cubic double perovskites of 5d transition metals. Here, by constructing and solving an ab initio low-energy Hamiltonian, we show that an antiferroic order of magnetic octupoles also forms in the t...
