Three-dimensional flux-sensor composed of high-Tc superconductor
Three-dimensional flux-sensor has been studied aiming at the practical application of high-Tc oxide superconductor Y-Ba-Cu-O. The thick filmy and cyclindrical shaped sensors were made and examined. The voltage versus current characteristics were investigated as the function of magnetic field at liquid nitrogen temperature. The flux flow was observed in the wide range of magnetic field from 0.001 to 1 Tesla and the magnetic field could be evaluated by the output voltage. The dependence of the voltage on the angle between the current and magnetic field direction was also examined. The flux flow was affected by the direction of external magnetic field resulted in the change of the output voltage. The output voltage was found to show hysteresis against external field. On the basis of these penomena, three-dimensional flux-sensor was designed and fabricated. The hysteresis and the angle dependence is discussed.
