THREE-COMPONENT MAGNETOMETER BASED ON SPHERICAL YIG RESONATOR AND METHOD OF DETECTION OF FULL MAGNETIC FIELD VECTOR Russian patent published in 2014 - IPC G01R33/24 

FIELD: instrumentation.

SUBSTANCE: magnetometer includes microwave generator with a spherical resonator based on an yttrium-iron garnet with three axes of light magnetisation, which are in the generator feedback line, and a magnetic system for transition of the resonator into the saturation mode, representing three inductance coils, which are arranged near the resonator so that their axes of symmetry are aligned along the axes of light magnetisation of the resonator. The outlet of the microwave generator is connected to a frequency meter. Signals from a square-ware generator are sent to coils via a counter of pulses and a demultiplexer, and the square-ware generator is also connected to a frequency meter via an inverter. A signal from the frequency meter via a coupling board is sent to a PC for processing.

EFFECT: increased sensitivity and magnetic directivity of a device, simplified method to determine direction of a magnetic field induction vector or direction to an iron-containing object.
