Abstract

The authors successfully dope the magnetically silent double perovskite semiconductor Sr₂GaSbO₆ to induce ferromagnetism and tune its bandgap, with Ga³⁺ partially substituted by the magnetic trivalent cation Mn³⁺, in a rigid cation ordering with Sb⁵⁺. The new ferromagnetic semiconducting Sr₂Ga₁₋_xMn_xSbO₆ double perovskite, which crystallizes in tetragonal symmetry (space group I4/m) and has tunable ferromagnetic ordering temperature and bandgap, suggests that magnetic ion doping of double perovskites is a productive avenue toward obtaining materials for application in next-generation oxide-based spintronic devices.
