Magnetic order induced crystal symmetry lowering in ACr${}_2$O${}_4$ ferrimagnetic spinels

S. Bordacs, D. Varjas, I. Kezsmarki +6

We demonstrate that the onset of complex spin orders in ACr${}_2$O${}_4$ spinels with magnetic A$=$Co, Fe and Cu ions lowers the lattice symmetry. This is clearly indicated by the emer…
