We study zero-field cross-relaxation features of negatively charged nitrogen-vacancy (NV) center ensembles in diamond. This feature holds promise for magnetometry applications where either the microwaves or the bias magnetic field used in conventional NV center magnetometry disturb the system under study; for example, the study of high-temperature superconductors, zero- to ultralow-field (ZULF) NMR, investigation of biological samples, and magnetic materials.
