Summary

Results show that the splay in the orientation of the columnar defects (produced by heavy ion irradiation) has a significant effect on dynamics of the vortices. 0.58 GeV ¹¹⁶Sn{sup 30+} and 1.08 GeV ¹⁹⁷Au{sup 23+} ions were used to irradiated YBaCuO single crystals. At high temperatures, the larger splay of the Sn tracks (10°) results in a current density one order of magnitude larger and a creep rate on order of magnitude smaller than the Au irradiation (1°). This indicates that a considerable further improvement of the current carrying capacity of high temperature superconductors can still be obtained.
