✦ Synopsis

High quality epitaxial thin films of YBa2Cu307 have been deposited on single crystal Mg0 (i00), SrTi03 (i00), and LaAIO 3 (i00) by laser ablation. The transport critical current density at 77 K is in the range of 106 -107 A/cm 2 depending on the type of substrate. An alternative way to measure the critical current density based on high probe field ac-susceptibility measurements, avoiding the needs of patterning, is described, and the results are compared to transport measurement.
