Physical foundations of an application of scanning probe with spin centers in SiC for the submicron quantum probing of magnetic fields and temperatures

Optical and radio-frequency physical effects that allow spin manipulations at room temperature using magnetic resonance, effects of anticrossing levels in the ground and excited quadruplet spin states, and cross-relaxation resonances in ensembles of spin color centers in silicon carbide micro- and nanocrystals have been demonstrated. A scanning device where ensembles of spin centers placed on the tip of the cantilever probe of an atomic force microscope serve as sensors of magnetic and temperature fields with a submicron spatial resolution has been considered.
