Abstract

The critical current densities (J c) have been measured at 77K in high pressure oxygen sputtered thin films of YBa2Cu3O7−x superconductor using the non-resonant rf absorption technique. High values ofJ c (∼ 105 A/cm2) are observed in these relatively large area (∼ 1·2 cm2) films.

Keywords
