Time-reversal symmetry breaking hidden order in Sr2(Ir,Rh)O4
Abstract
Exploring ordered states in similarly structured oxides aids the understanding of structure-property correlations. Here the authors discover an unconventional magnetic order in Sr2(Ir,Rh)O4, which is analogous to a loop-current phase in cuprate superconductors with the same lattice structure.
