Abstract
Magnetic field gradients are determined experimentally from the measured interaction between a magnetic field and probes with known magnetic characteristics. Measures are described that ensure a relative rms frequency deviation of an electromechanical resonator of <10−5 in a long-duration (for many days) experiment, which is several orders of magnitude better than the parameters of well-known gauges. The developed gauge can also be used in strain measurements, thermogravimetry, cryogravimetry, and to measure the magnetic properties of materials.
