A coupled radio frequency field and light polarization magnetometer. The polarization direction P and the direction of the radio frequency field B.sub.1 are kept parallel to one another and perpendicular to the field B.sub.0 which is to be measured. The polarizer is connected to the coil, which produces B.sub.1, and the assembly is rotated by a piezoelectric motor.

Coupled radio frequency field and light polarization magnetometer

Slaved radio frequency field and light polarization magnetometer. The polarization direction (P) is slaved perpendicular to the field (Bo) to be measured, as well as the radio frequency field (Brf). Application to the measurement of weak magnetic fields such as the geomagnetic field.
