Magnetic field sensing under high-pressure and high-temperature conditions has conventionally been challenging in the high-temperature regime due to the temperature limitations of measurement apparatuses. In this study, we developed an integrated diamond anvil cell (DAC) device that combines a nitrogen-vacancy (NV) center in diamond with boron-doped diamond (BDD), both of which have proven track records under single extreme environments, and attempted magnetic field sensing under simultaneous extreme conditions. By utilizing this novel device, we successfully captured local magnetic field changes near a ferromagnetic sample under actual high-pressure and high-temperature environments, and clearly observed the subsequent shifts in the optically detected magnetic resonance (ODMR) spectra.
