| Shrnutí: | In recent years, spin defects in SiC have become important systems for quantum information. In this work, the magnetic-field- and temperature-dependent spin relaxation of divacancy spins in 4H-SiC is experimentally studied. We first measure the spin relaxation time
as the magnetic field varies from 43 G to 640 G and find that
significantly decreases at magnetic field values near 482 G and 241 G due to the cross-relaxation with the electric and nuclear spin baths. We then investigate the temperature-dependent relaxation
and coherence time
. The results show that both
and
decrease as the temperature increases from 295 K to 458 K. The experiments provide the basis for understanding the spin relaxation property of divacancy spins, which is useful for the spin relaxation-related quantum technologies. |
