Sampling Magnetometer Based on the Hall Effect

Conference paper


A pulsed sampling magnetometer is described, based on the Hall effect in vacuum evaporated films of InSb. Pulsed operation of thin film Hall effect detectors provides an increase in sensitivity over cw operation of conventional Hall devices. This is due, in part, to the improved thermal dissipation of the fim, the reduction in joule heating, and the greatly improved noise discrimination because of stroboscopic sampling. A sensitivity of better than 10−4 v/gauss, over a frequency range between 100 cps to 5 Mc and an angular orientation sensitivity of 10−5 v/degree have been obtained in devices built to date.
