A Recording Torque Magnetometer
Review of Scientific Instruments, 1950This instrument produces, automatically, a curve of torque versus angle of orientation for a thin iron or steel disk in a strong magnetic field. A resistance strain gauge converts the torque acting on the disk specimen to a small d.c. voltage, which is recorded on a ``strip-chart'' recording potentiometer.

Proceedings of the IRE, 1953
Faraday rotation in ferrites at microwave frequencies is applied experimentally to a new magnetometer technique expected to attain extreme sensitivity. The microwave output voltage is linearly, related to the magnetic field. Sensitivity is a function of microwave carrier level, length and initial permeability of the ferrite rotator.
