Abstract

A description is given of electronic equipment which enables the simultaneous measurement of the Hall coefficient and the electrical conductivity by using an alternating magnetic field and alternating current. The instrument is adapted for measuring a minimum Hall coefficient of 3.10−11 Vcm/AGand electrical resistance 10−5 Ωto 103 Ω;the smallest measurable Hall voltage is 1 μ V.Deviations from the results, obtained by the classical d—cmethod, do not exceed 5%.
