Abstract
By means of four-point transport measurements on bulk, high-Tc superconducting samples of composition (Sm0.33Eu 0.33Gd0.33)Ba2Cu3Oy exhibiting self-organized nanostripes formed by nanoclusters of the light-rare-earth-rich phase, we find that at temperatures close to the transition temperature the currents flowing parallel to the nanostripes are clearly larger than in the perpendicular direction. Constructing a pinning force diagram from the jc(Ha)-data obtained, we find strong evidence for a dominating δTc-pinning when the currents are flowing parallel to the nanostripes.
