The double-perovskite A2BBO6 with heavy transition metal ions on the ordered B sites is an important family of compounds to study the interplay between electron correlation and spin-orbit coupling. Here we prepared high-quality Sr2MgReO6 powder and single-crystal samples and performed nonresonant and resonant synchrotron X-ray diffraction experiments to investigate its magnetic ground state. By combining the magnetic susceptibility and heat capacity measurements; we conclude that Sr2MgReO6 exhibits a layered antiferromagnetic order at temperatures below ∼55 K with a propagation vector q=(001); which contrasts the previously suspected spin-glass state. Our works clarify the magnetic order in Sr2MgReO6 and demonstrate it as a candidate system to look for magnetic octupolar orders and exotic spin dynamics. © 2020 American Physical Society;

摘要：

The double-perovskite A(2)BB'O-6 with heavy transition metal ions on the ordered B' sites is an important family of compounds to study the interplay between electron correlation and spin-orbit coupling. Here we prepared high-quality Sr2MgReO6 powder and single-crystal samples and performed nonresonant and resonant synchrotron x-ray diffraction experiments to investigate its magnetic ground state. By combining the magnetic susceptibility and heat capacity measurements, we conclude that Sr2MgReO6 exhibits a layered antiferromagnetic order at temperatures below similar to 55 K with a propagation vector q = (001), which contrasts the previously suspected spin-glass state. Our works clarify the magnetic order in Sr2MgReO6 and demonstrate it as a candidate system to look for magnetic octupolar orders and exotic spin dynamics.
