  • Magnetic field measurement device and magnetic field measurement method based on solid-state spins
    Patent number: 11313921
    Abstract: A magnetic field measurement device and a magnetic field measurement method based on solid-state spins are provided. Zeeman splitting between electron energy levels of electrons of a magnetic sensitive unit is different under the action of external magnetic fields having different intensities. Continuous excitation and manipulation is applied to the electrons by means of a control field and control laser, so that spins of a system can reach a balanced state. The spin population of the system is influenced by the external magnetic fields. Therefore, fluorescence signals with intensities changing with the spin population of the system can be obtained, and fluorescent signals having different intensities can be obtained according to the different intensities of the external magnetic fields.
