Tuller, Gerald F. Dionne, J. Michael D. Coey, and Caroline A. Ross Multifunctional oxides could provide the basis of many of tomorrow’s technologies, and understanding the physics of their oxygen defects is often the key to tailoring device performance. The authors study the electronic structure, magnetism, and magnetooptical properties of SrTi 1 − x Fe x O 3 − δ , an important “non-dilute” magnetic semiconductor, and illustrate its application in a nonreciprocal photonic device. This insight into oxygen-vacancy-mediated magnetism will be relevant for engineering the properties of a whole range of materials by controlling their stoichiometry. [Phys. Rev.
