ABSTRACT:
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.
