Abstract
Optically addressable spins in materials are important platforms for quantum technologies, such as repeaters and sensors. Identification of such systems in two-dimensional (2d) layered materials offers advantages over their bulk counterparts, as their reduced dimensionality enables more feasible on-chip integration into devices. Here, we report room-temperature optically detected magnetic resonance (ODMR) from previously identified carbon-related single defects in 2d hexagonal boron nitride (hBN). We show that single-defect ODMR contrast is up to 100x stronger than that of ensembles and displays a magnetic-field dependence with both positive or negative sign per defect. Further, the ODMR lineshape comprises a doublet resonance, indicating a S=1 state with low but finite zero-field splitting. Our results offer a promising route towards realising a room-temperature spin-photon quantum interface in hexagonal boron nitride.
