This work surveys recent studies of the intragrain current density J and vortex pinning in high Tc superconductors. Materials include Y[sub 1]Ba[sub 2]Cu[sub 3]O[sub 7-[delta]] and Bi[sub 2]Sr[sub 2]Ca[sub 1]Cu[sub 2]O[sub 8] single crystals and aligned polycrystals. To probe the flux pinning, we modified the strength, number, and morphology of defects. Varying the oxygen content (7-[delta]) in YBa[sub 2]Cu[sub 3]O[sub 7-[delta]] or irradiating the materials with ions, having either light or heavy masses, gives systematic changes in the character of the all-important defects.
