Abstract

Mn₂NiReO₆, prepared at high pressure and temperature, has a highly-distorted double perovskite structure. Canted antiferromagnetic order is observed below T_M1 = 80 K and an unusual continuous spin rotation of Mn spins occurs down to T_M2 = 42 K where a collapse in weak ferromagnetism evidences an unprecedented switching of the weak ferromagnetic moment directions.
