Abstract

The authors investigate electronic phases of spin--orbit-entangled 5d electrons in the transition metal compound Ba2MgReO6. They observe quadrupolar order composed of antiferroically arranged Qx2--y2 and ferroically arranged Q3z2--r2 moments in addition to unusual canted antiferromagnetic order stabilized by the quadrupolar order.
