Recent experiments have shown evidence for induced ferromagnetism in thin films of carbon and nitrogen-doped zinc oxide. We have discovered similar behavior in nitrogen-doped MgO films grown by plasma-assisted thermal evaporation. Here, we incorporate these films as tunneling barriers into single-crystal multilayer magnetic tunnel junctions and present experimental results showing the magnetoresistance and current-voltage characteristics for these structures.
