摘要：
A RF-SQUID consists of a superconductive ring (2) with a Josephson junction (5) and coupled to an electric resonant circuit (1) formed by a superconductive microwave resonator. The object of the invention is to create a RF-SQUID magnetometer with an improved field sensitivity which may be produced from high-temperature superconductive materials. For that purpose, the microwave resonator is designed as a closed superconductive circuit (1). Because of the closed circuit, a lambda resonator is obtained for the first time, which functions besides as a pick-up coil. In comparison with a design having a lambda /2 resonator, magnetic flow collection is considerably increased.
