Abstract

A surface coil composed of a miniature spiral YBa₂Cu ₃O_y (YBCO) thin film resonator and a Bi₂Sr ₂Ca₂Cu₂O₃ (BSCCO) tape resonator were designed. The spiral YBCO resonator was fabricated onto one side of a 2 × 2cm²LaAlO₃ substrate, which was then coupled to the receiver via a tank circuit and a fine-tuning copper coil to image small samples. Additionally, a BSCCO tape resonator of 20cm in diameter was coupled to a receiver coil and a fine-tuning coil to image large samples. An improvement of the signal-to-noise ratio for high-T_c resonators over a conventional copper resonator is demonstrated.
