Insulator-to-metal transitions induced by spontaneous magnetization above room temperature have rarely been observed. Here, the authors show that this transition, along with concurrent high-temperature ferrimagnetic order, is realized in the novel 3d/5d hybridized quadruple perovskite oxide CaCu3Ni2Os2O12.
