MAGNETOMETER ON THIN MAGNETIC FILM Russian patent published in 2021 - IPC G01R33/02 

FIELD: measurement.

SUBSTANCE: invention relates to measurement equipment, and specifically is intended for measurement of values and directions of weak magnetic fields in a wide frequency range, and can be used in magnetometry. Magnetometer on a thin magnetic film comprises a printed-circuit board with a microwave generator mounted thereon, the load of which is microwave resonators, a thin magnetic film, amplitude detectors connected to microwave resonators, operational amplifiers, a magnetic system which forms a constant magnetic field, wherein thin magnetic film is located outside of microwave resonators, but in close proximity to their inductive parts, which are made in form of strip conductors on printed circuit board, constant magnetic field is directed along the axis of difficult magnetisation of the thin magnetic film, and the high-frequency magnetic field is directed at an angle to the axis of easy magnetization, wherein direction of maximum sensitivity coincides with direction of easy magnetisation axis.

EFFECT: technical result is increased sensitivity of magnetometer on thin magnetic film.
