<p>The family of room temperature atomic scale magnetometers is currently limited to nitrogen<br> vacancy (NV) centers in diamond. However, NV centers are insensitive to strong off-axis magnetic<br> fields. In this work, we show that the well-known TR12 radiative defect in diamond, exhibits<br> strong optically detected magnetic resonance (ODMR) signal under optical saturation. We also<br> demonstrate that the spin system responsible for the magnetic resonance is an excited triplet state<br> that can be coherently controlled at room temperature on a single defect level. The high ODMR<br> contrast, which is maintained even for strong off-axis magnetic fields, suggests that TR12 centers<br> can be used for vector magnetometry even at high field.</p>
