Karazin popup.description2 The object of the investigations was high temperature superconductor - perfect YBaCuO single crystals. The main goal of the investigations was preparing the samples with controlled suppression of superconducting order parameter at the twin boundaries with controlled distances and desired orientation of persistent current with respect to twin boundaries. The method of the investigations was analysis of electro resistive transport properties of YBaCuO single crystals with different concentration of point defects and different orientations of twin boundaries respect to persistent current and magnetic field. Experimental results of this report can be explained by existence of low temperature superconducting phase with suppressed superconducting order parameter on the twin boundaries. This result can be used in future investigations for weak links identification at twin boundaries in samples with different geometries.
