Abstract
We describe measurements of the specific resistivity of epitaxially gr own YBa2Cu3O7-x thin films in the presence of a magnetic field of up t o 1 T at 270 MHz. At 77 K and 300 mT a 70-fold reduction of the specif ic resistance, as compared to liquid nitrogen cooled copper, is achiev ed. These results suggest a possible application of these films as sma ll receiving coils with improved sensitivity in low field nuclear magn etic resonance imaging systems.
