Quantum Sensing
Measurements of magnetic properties on the atomic scale require a sensor with the intrinsic sensitivity for single spin detection, a size comparable to systems under investigation, and the capability for measurements without strongly influencing the spin properties of the studied systems. We delve into such quantum sensing experiments by exploiting two different techniques, namely:
NV- magnetometry
ESR- STM
