Abstract Controllable solid-state spin qubits are currently becoming useful building blocks for applied quantum technologies. Here, we demonstrate that in a specific type of silicon-vacancy in the 6H-SiC polytype the excited-state fine structure is i

All-optical thermometry technique based on the energy level cross-relaxation in atomic-scale spin centers in SiC is demonstrated. This technique exploits a giant thermal shift of the zero-field splitting for centers in the triplet ground state, S=1,

The presence of aluminum and gallium isotopes with large nuclear magnetic and quadrupole moments in the nearest environment of impurity ions Mn2+ and Ce3+ in garnets made it possible to use hyperfine and quadrupole interactions with these ions to det

We uncover the fine structure of a silicon vacancy in isotopically purified silicon carbide (4H-^{28}SiC) and reveal not yet considered terms in the spin Hamiltonian, originated from the trigonal pyramidal symmetry of this spin-3/2 color center. Thes

A family of atomic-scale color centers, the spin state of which can be controlled via optical and microwave channels, has been found in the rhombic polytype of silicon carbide 21R-SiC considered as a natural superlattice. Zero-phonon lines are observ
