Decoherence of nitrogen vacancy (NV) centers limits sensitivity in magnetometry applications ranging from nanoscale NMR to navigation. A main source of decoherence arises from the substitutional nitrogen electron spin (P1 center) bath in the diamond lattice. Much effort has focused on decoupling NV and P1 spin interactions, but a full description of the underlying bath evolution remains incomplete. Here, we study interactions of a single P1 center with surrounding bath spins using a nearby NV center as a polarization source and probe. We present time-resolved measurements of the spin under external laser and microwave excitation, revealing charge and spin dynamics at a single-P1 level. Alongside experiments we perform cluster correlation expansion (CCE) calculations to determine the structure of our spin bath, demonstrating characterization methods that account for local disorder.
