Classification: CPC G | IPC G

Claim 6:
7. The measuring method as claimed in claim 5, wherein the measuring method furthermore comprises:
irradiating the NV center with a microwave radiation, the frequency of which is varied over a predetermined frequency range, wherein at at least one resonant frequency in the predetermined frequency range a resonant microwave absorption occurs at the NV center and the resonant microwave absorption increases the occupation probability for quantum states having the second spin quantum number relative to the occupation probability for quantum states having the first spin quantum number; and
determining the at least one resonant frequency on the basis of at least one change in the phase shift during the variation of the microwave radiation over the predetermined frequency range, wherein the measured value is determined on the basis of the at least one resonant frequency.
