Observation of Enhanced Long-Range Ferromagnetic Order in B-Site Ordered Double Perovskite Oxide Cd<sub>2</sub>CrSbO<sub>6</sub>
A B-site ordered double perovskite oxide Cd<sub>2</sub>CrSbO<sub>6</sub> was synthesized under high-pressure and high-temperature conditions. The compound crystallizes to a monoclinic structure with a space group of <i>P</i>2<sub>1</sub>/<i>n</i>. The charge configuration is confirmed to be that of Cd<sup>2+</sup>/Cr<sup>3+</sup>/Sb<sup>5+</sup>. The magnetic Cr<sup>3+</sup> ions form a tetrahedral structural frustrated lattice, while a long-range ferromagnetic phase transition is found to occur at <i>T</i><sub>C</sub> = 16.5 K arising from the superexchange interaction via the Cr-O-Cd-O-Cr pathway. Electrical transport measurements indicate that Cd<sub>2</sub>CrSbO<sub>6</sub> is an insulator that can be described by the Mott 3D variable range hopping mechanism. First-principles calculations reproduce well the ferromagnetic and insulating ground state of Cd<sub>2</sub>CrSbO<sub>6</sub> with an energy band gap of 1.55 eV. The intrinsic ferromagnetic insulating nature qualifies Cd<sub>2</sub>CrSbO<sub>6</sub> as a promising candidate for possible spintronics applications.
