Analysis shows distinct relaxation behaviors in boron-vacancy centers across temperatures and fields, suggesting potential for quantum sensing applications.
Key Points
Investigating spin relaxation reveals a transition from low-temperature interactions to phonon-dominated dynamics at higher fields.
Distinct relaxation regimes emerge, driven by spin-spin interactions and disorder at low temperatures and single-phonon processes at high fields.
Temperature and magnetic field scaling behaviors of the relaxation rate provide insights into boron-vacancy center interactions.
Results support the development of high-field, sub-terahertz quantum sensors based on two-dimensional spin-defect platforms.
