Abstract
A technique for accurately measuring small superconductive inductances is presented. The inductance to be measured is inserted into a two‐junction interferometer into which control current is directly injected. The method was used to measure the penetration depth of a Pb‐In‐Au alloy film and the effect of magnetic field fringing into a narrow superconductive stripline.
