Abstract

PURPOSE:To simplify the structure of a magnetic sensor part by forming a superconductive loop between a superconductor of thin film and a pickup coil. CONSTITUTION:The pickup coil connection terminals 2a and 2b of the supercon ductor 2 of thin film are connected to the pickup coil 1 by superconductive connection wires 4 and 5, and exciting terminals 2b and 2d are connected to a basic frequency current generation circuit 3, and an AC exciting current is of prescribed frequency is inputted. The terminals 2b and 2d are also con nected to an AC amplifier 6, and output corresponding to resistance in which a current on the superconductor 2 changes based on the superconductive state or the stationary state of the superconductor 2 is taken out, and it is amplified by the AC amplifier 6, and is rectified at a synchronous rectifier circuit 7, then, an output voltage (e) is derived. At this time, when magnetic flux phix by a magnetic field is inputted to the coil 1, an induced current i flows, and the current ix is superposed on a current is, then, the voltage (e) changes. By deriving a changed voltage as the output, the strength of a micro magnetic field can be detected. Therefore, since it is not required to provide a complicated Josephson junction such as a skid magnetometer, the structure can be simplified.
