  Title Ideal two dimensional flux pinning induced by annealing in superconducting amorphous Zr75Rh25 Type Journal Article
  Year 1986 Publication Solid State Communications Abbreviated Journal Solid State Commun.  
  Volume 57 Issue 9 Pages 753-756  
  Keywords ZIRCONIUM COMPOUNDS – Physical Properties; CRITICAL CURRENT; FLUX PINNING; MELT SPINNING; PINNING FORCES; SUPERCONDUCTING MATRIX; SUPERCONDUCTING MATERIALS  
  Abstract By annealing amorphous Zr75Rh25 prepared by melt spinning an ideal behaviour of the critical current was observed, in which the measured pinning forces are seen to follow the two dimensional Larkin-Orchivnikov theory. In the region where this theory is valid the changes in the pinning forces can be explained by the changes in the superconducting matrix and it can be assumed that the pinning centers do not change with the heat treatment.

  Title Angular variation of pinning near the irreversibility temperature in single crystal Y Ba2Cu3O7-? with splayed columnar defects Type Journal Article
  Year 1998 Publication Physica C Abbreviated Journal Physica C  
  Volume 304 Issue 1-2 Pages 112-118  
  Keywords Columnar defects; Critical current density; Flux pinning; Pinning force; Anisotropy; Critical current density (superconductivity); Crystal defects; Single crystals; Columnar defects; Flux pinning; Yttrium barium copper oxides  
  Abstract We have studied vortex pinning through ac susceptibility measurements in single crystals of YBCO with columnar defects (CDs). The CDs have 0, 10 and 20 splay angle and average direction 108 off the c-axis. By studying the angular variation we can compensate for the anisotropy and effects of twins, etc. Using a simple expression we can obtain the angular spread when the field direction is outside the splay angle. An increase of pinning when the field direction is inside

the angle defined by the CDs can be attributed to vortex entanglement due to the splay and the suppression of the sliding of double kinks.
