Description:

A high-Tc superconducting (HTS) flux transformer is prepared using a commercially available REBa2Cu3Oy HTS tape. The device configuration includes a 10 cm diameter pickup coil and a 3 cm diameter multi-turn input coil which are formed by the ʻcut-and windʼ method. The static magnetic field transfer from the pickup coil to the input coil is measured, and amplification of the magnetic field in the input coil compared to the applied field in the pickup coil is confirmed in the device which equipped with the multi-turn input coil. The magnitude of this magnetic field amplification achieved 125% of the applied field. This result suggests that the HTS flux transformer proposed in this study is effective in the sensitivity enhancement of the magnetometer for static magnetic fields.
