Abstract

An optical quantum magnetometer with submicron spatial resolution is proposed that is based on the phenomenon of optical response in a solid-state spin system under conditions of spin sublevel anticrossing without using a resonance frequency. The system operation is demonstrated by example of spin defects in silicon carbide of various polytypes.
