High-temperature superconductors play an important role in various areas of physics and technology. One of the directions of improving the quality of these materials is the creation of artificial defects, e.g. by doping. In this way, the value of the critical current can be increased. In this paper, the authors prepared the samples by the conventional glass–ceramic route. They showed that the addition of carbon nanotubes can change the critical current density by up to about 30% without significant morphological change of the material. This research makes a step forward toward better superconductive materials.
