Abstract

We report a simple alternating current magnetometer. It is based on the principle of an ordinary Hartshorn bridge. The use of a two-channel oscillator allowed us a simple construction and a sensitivity of magnetic moment better than 10-6emu, normally sufficient for superconductivity studies. The whole system is controlled by a personal computer to collect the data automatically.
