Abstract
We have built and tested a thinโfilm high temperature superconducting (HTS) surface coil for MRI at 0.064T. When placed as close as possible to a conductive sample, the 6.7โcm outer diameter HTS coil had a measured signalโtoโnoise ratio (SNR) 1.8; times higher than a room temperature copper coil of similar size and location. Our results predict that in some cases, SNR gains of about a factor of 2 can be attained in lowโfield MRI systems by substituting HTS surface coils for copper coils.

Thin flms of rare-earth-free high T~ superconductors such as Bi-Sr-Ca-Cu-O and TI-Ba-Ca-Cu-O systems have been prepared by RF-magnetron sputtering and subsequent annealing. These thin films showed a polycrystalline structure and had highly orientated c-axes perpendicular to the substrates. These thi
