Abstract

A B-site ordered double perovskite oxide Cd₂CrSbO₆ was synthesized under high-pressure and high-temperature conditions. The compound crystallizes to a monoclinic structure with a space group of P2₁/n. The charge configuration is confirmed to be that of Cd²⁺/Cr³⁺/Sb⁵⁺. The magnetic Cr³⁺ ions form a tetrahedral structural frustrated lattice, while a long-range ferromagnetic phase transition is found to occur at T_C = 16.5 K arising from the superexchange interaction via the Cr-O-Cd-O-Cr pathway. Electrical transport measurements indicate that Cd₂CrSbO₆ 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 Cd₂CrSbO₆ with an energy band gap of 1.55 eV. The intrinsic ferromagnetic insulating nature qualifies Cd₂CrSbO₆ as a promising candidate for possible spintronics applications.
