Abstract

This paper describes the design and operation of pendulum-type magnetometer to measure the magnetic susceptibility of weakly magnetic solids under high gas pressure. A feature of the device is the placement of a mechanical pendulum system directly into the high-pressure chamber. As an example of the magnetometer application, the experimental dependence of susceptibility on the pressure up to 2 kbar in the temperature range 60–300 K is presented for the V4S9Br4 compound.
