| Abstract(in English) | We developed a magnetometer based on inductance modulation of a coil made from a high-critical-temperature superconducting(HTS) material. The magnetometer consists of two HTS coils, namely, pickup and read-out (modulation) coilsl. The inductance of the modulation coil was modulated over time via a modulation current applied to a magnetic wire that was inserted into the coil. The magnetic field was then converted into a signal voltage using this time-dependent inductance. The relationship between the magnetometer performance and the modulation current conditions was studied. Under appropriate conditions, the magnetometer had responsivity of 2480V / T. The magnetic field noise was 0.8pT / Hz1 / 2 in the white noise region and 11pT / Hz1 / 2 at 1 Hz. |
