Nuclear spin sensing under hydrostatic pressure using nitrogen vacancy centers*

Nitrogen vacancy centers have attracted broad attention as quantum sensors particularly for quantum sensing under geochemical hydrostatic pressure conditions(hundreds of kbars) . Here we present AC sensing results up to 6 GPa with sensitivity to detect nuclear spin inside the diamond anvil cell. These experiments enable the possibility for all-optical high resolution magnetic resonance of nanoliter sample volumes to study geochemical processes.
