Abstract

Abstract The invention relates to a Josephson device and a method of manufacturing such a device which comprises two layers 11, 11′ of an oxidic superconducting material between which at least one non-­superconducting layer 13 of silver sulphate is provided. The non-­superconducting layer 13 is connected to the superconducting layers 11, 11′ through silver layers 12, 12′.
