Abstract

Mn₂CoReO₆, the fourth known magnetic transition-metal-only double perovskite oxide (space group P2₁/n) was synthesized at high pressure and temperature (8 GPa, 1350 °C). Large structural distortions are induced by the small A-site Mn²⁺ cations. Mn₂CoReO₆ exhibits complex magnetic properties with a robust antiferromagnetic order (T_N = 94 K) involving all cation sublattices.
