摘要：

The measurement of the Hall constant in insulating highly resistive films is a difficult and challenging task. Owing to the small currents that may be passed through the insulating films, the Hall voltages are often very small in magnitude. A simple electronic circuit using commercial lock-in amplifiers is described which allows measuring these minute Hall voltages. Other practical measuring suggestions are also presented.
