The electronic spins of the nitrogen-vacancy centers (NV centers) in\nChemical-Vapor-Deposition (CVD) grown diamonds form ideal probes of magnetic\nfields and temperature, as well as promising qu-bits for quantum information\nprocessing. Studying and controlling the magnetic environment of NV centers in\nsuch high purity crystals is thus essential for these applications. We\ndemonstrate optical detection of paramagnetic species, such as hydrogen-related\ncomplexes, in a CVD-grown diamond. The resonant transfer of the NV centers’\npolarized electronic spins to the electronic spins of these species generates\nconspicuous features in the NV photoluminescence by employing magnetic field\nscans along the [100] crystal direction. Our results offer prospects for more\ndetailed studies of CVD-grown processes as well as for coherent control of the\nspin of novel classes of hyper-polarized paramagnetic species.\n
