| description | The interface with spin defects in hexagonal boron nitride has recently
become a promising platform and has shown great potential in a wide range of
quantum technologies. Varieties of spin properties of $V_B^-$ defects in
hexagonal boron nitride (hBN) have been researched widely and deeply, like
their structure and coherent control. However, little is known about the
influence of off-axis magnetic fields on the coherence properties of $V_B^-$
defects in hBN. Here, by using the optically detected magnetic resonance (ODMR)
spectroscopy, we systematically investigated the variations in ODMR resonance
frequencies under different transverse and longitudinal external magnetic
field, respectively. In addition, we measured the ODMR spectra under off-axis
magnetic fields of constant strength but various angles, and observed that the
splitting of the resonance frequencies decreases as the angle increases,
aligning with our theoretical calculation based on the Hamiltonian, from which
we come up with a solution of detecting the off-axis magnetic field angle.
Through Rabi oscillation measurements, we found that the off-axis magnetic
field suppresses the spin coherence time. These results are crucial for
optimizing $V_B^-$ defects in hBN, establishing their significance as robust
quantum sensors for quantum information processing and magnetic sensing in
varied environments. |
