FIELD: instrumentation.
SUBSTANCE: invention represents a device and a method to measure direction and value of magnetic fields with application of magnetic resonance and may be applied for detection of iron-containing bodies and navigation in the Earth magnetic field. A magnetometer includes a microwave generator with a disc resonator of type [111] with three axes of light magnetisation on the basis of an yttrium-iron garnet, which is located in the generator feedback line, and a magnetic system for transfer of the resonator into a monodomain mode representing two inductance coils arranged near the resonator so that their axes are aligned at the angle 120° with a top in a geometric centre of the resonator. The outlet of the microwave generator is connected to a frequency meter started from a generator of start-up signals. From a square-ware generator signals are sent to coils, besides, to one of them - 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, increased efficiency of the method for detection of value and direction of magnetic field induction vector.
