Query: Ferromagnetic Double Perovskite Semiconductors with Tunable Properties   We successfully dope the magnetically silent double perovskite semiconductor
Sr2GaSbO6 to induce ferromagnetism and tune its band gap, with Ga3+ partially
substituted by the magnetic trivalent cation Mn3+, in a rigid cation ordering
with Sb5+. Our new ferromagnetic semiconducting Sr2Ga1-xMnxSbO6 double
perovskite, which crystallizes in tetragonal symmetry (space group I4/m) and
has tunable ferromagnetic ordering temperature and band gap, suggests that
magnetic ion doping of double perovskites is a productive avenue towards
obtaining materials for application in next-generation oxide-based spintronic
devices.
