The room temperature ferromagnetism at the interface between CuO and Cu2O microspheres is reported in this letter. Magnetic measurement results indicate that the interface-based ferromagnetism can be tuned by changing the phase rations of the CuO/Cu2O compounds synthesized by one-step hydrothermal method at different reaction times. The indirect double-exchange model was employed to explain the observed ferromagnetism. This finding suggests that tailoring the interfaces is an effective route to engineer architecture with enhanced magnetic properties and establish a striking example of emergent phenomena at oxide interfaces.
