First wireless device to make magnetism appear in non-magnetic materials

Researchers from the UAB and ICMAB have managed to take wireless technology to the fundamental level of magnetic devices. The appearance and control of magnetic properties in layers of cobalt nitride (initially non-magnetic) by means of voltage, without connecting the sample to electrical wiring, published in Nature Communications, represents a paradigm shift that can facilitate the creation of magnetic nanorobots for the biomedicine and computer systems where basic information management processes do not require wiring.
