Radio spectroscopy of the optically aligned spin states of color centers in silicon carbide

The unique quantum properties of nitrogen-vacancy color centers (NV centers) in diamond have motivated the search for similar color centers with enhanced properties in SiC. In this paper, experimental evidence is presented that vacancy-related spin centers in SiC not only have properties similar to those of diamond NV centers but also exhibit many additional properties, making these quantum systems promising for various applications in spintronics, sensorics, and quantum information processing under ambient conditions.
