Abstract
High-quality LuBa2Cu3O7−δ(LBCO) thin films have been grown on < 100#62; LaAlO3 by pulsed laser deposition. Microstructural studies have indicated a high degree of c-axis orientation and an in-plane alignment. Transport measurements carried out on 10 μm wide microbridges of LBCO films have shown high critical current densities in the range 2-5×106 A cm−2 at 77 K. Self-field induced flux creep caused by transport currents has also been studied. However, the thickness-dependent effective microwave surface resistance, Reff, measured using a microstrip resonator technique at the X band has shown a minimum at 3000 Å indicating film degradation above 3000 Å.
