- Abstract
Coherent spin manipulations of ensembles of color centers in the form of neutral VSi–VC divacancies with the spin in hexagonal silicon carbide 6H–SiC enriched in the 13C isotope (12%) are studied in strong magnetic fields using electron spin echo and Rabi oscillation methods. Rabi oscillation experiments show that spin coherence is created in SiC with a tenfold increase in the content of the 13C isotope with a nuclear magnetic moment. The spin–lattice relaxation and spin–spin relaxation times are measured under conditions of optical alignment of spins at the temperature T = 150 K in a magnetic field of about 3 T and are ms and µs, respectively. The optical alignment of populations of spin levels makes it possible to manipulate electron and nuclear spins in the environment using optical, microwave, and radio-frequency radiation.
