Notes:
A moving-sample susceptometer based on a Hartshorn inductance bridge is described. This instrument makes it possible to measure magnetic susceptibility as a function of temperature. The lower limit of detection is approximately 50 parts per million of powdered YBa2Cu3Ox superconductor contained in a 5-mg sample, corresponding to approximately 10−6 emu/g. Measurements can be conducted in the 4.2–300 K temperature range. The apparatus can be built inexpensively of commonly available parts. Construction, operation, and possible applications are discussed.
