OPTICAL METHOD FOR MAGNETIC FIELD MEASUREMENT Russian patent published in 2021 - IPC G01R33/34 

FIELD: constant magnetic field measurement.

SUBSTANCE: invention relates to methods for measuring a constant magnetic field and can be used in the creation and operation of magnetic sensors and magnetometers. The optical method for measuring the magnetic field includes the effect of a magnetic field on the active element of the detector and registration of its magneto-optical characteristics, while the absorption spectrum of nanoparticles in the measured magnetic field is recorded and the magnitude of the magnetic field induction is determined from the frequency interval between the split components of the spectrum, and the active element of the detector is made of spherical silver nanoparticles.

EFFECT: expansion of methods and simplification of the processes of non-contact measurement of a constant magnetic field.
