Natural diamonds may contain a wide variety of defects of which only a hand full have been intensively studied. The most well known color center in diamond is the negatively charged nitrogen vacancy center, and it is of particular interest as it provides spin polarization and an optical spin read-out mechanism at ambient temperature (via optically detected magnetic resonance - ODMR). This ability to manipulate individual spins in the solid state has a wide range of exciting applications in quantum sensing, quantum information processing, and quantum communication. Only a few other color centres in diamond have been demonstrated to provide the ability to manipulate individual spins, including the silicon-vacancy (SiV)and an unidentified defect named ST1.
In this talk I will present results of low temperature spectroscopy measurements on a novel defect showing these properties which is found in natural diamond. The ODMR properties of this defect resemble those of the ST1 center. One aim of these measurements is to identify the defect responsible.
