  Title Enhancement of c-axis vortex correlation by twin boundaries and columnar defects in YBa2Cu3O7-delta Type Journal Article
  Year 1997 Publication PHYSICAL REVIEW B Abbreviated Journal  
  Volume 55 Issue 9 Pages 5663-5665  
  Abstract We report on transport measurements using the flux transformer configuration in a twinned single crystal of YBa2Cu3O7-delta with columnar defects. The vortex liquid shows velocity correlation along the c axis (the direction of the applied magnetic field and the columnar defects) at temperatures that correspond to an uncorrelated liquid in unirradiated samples of the same thickness. These results and previous work about the effect of twin boundaries on vortex velocity correlation show that phase coherence in the field direction is not an intrinsic property of vortex liquids but one induced by extended defects.
