Emergent ferromagnetism in ZnO/Al2O3 core-shell nanowires : towards oxide spinterfaces

We report that room-temperature ferromagnetism emerges at the interface formed between ZnO nanowire core and Al2O3 shell although both constituents show mainly diamagnetism. The interface-based ferromagnetism can be further enhanced by annealing the ZnO/Al2O3 core-shell nanowires and activating the...
