Abstract
Section titled āAbstractāAbstract A robust technique is introduced for vector magnetometry based on polarimetry and optically detected magnetic resonance of ensembles of negatively charged nitrogenāvacancy (NV - ) centers in diamond without a magnetic bias field. Ensembles provide a far greater signalātoānoise ratio than single centers, and their creation requires less effort. Previous methods for vector magnetometry using ensembles of NV - centers relied on a calibrated magnetic bias field or on complex detection techniques to distinguish the crystal axes. Instead, this work uses outāofāplane polarized light to selectively excite NV - centers oriented along specific crystal axes. This approach is general for other spinā1 color centers with symmetry, and it is compatible with standard microscopy methods, such as scanning probe, superresolution, confocal, and wideāfield imaging.
