Abstract: This article discusses an effective method for obtaining superconducting composites based on Y1Ba2Cu3O7-δ (YBCO) by optimizing the total preparation time in comparison with similar scientific works while searching for effective modifying micro-additives. YBCO-based composites were doped with microparticles of aluminum, nickel, and iron. It was established that the initial ratio of green components, heat treatment, and holding time directly affect the qualitative and quantitative formation of the useful superco… Show more

The study of YBCO thin films under laser irradiation reveals a significant interplay between their electrical and optical properties. Despite being exposed to energies exceeding the superconducting gap, YBCO retains its superconductivity and shows unexpected resilience. This, together with the photovoltaic effect induced by laser light, opens up possibilities for YBCO-based devices beyond current limits. YBCO thin films were fabricated on SrTiO 3 substrates and exhibited a high critical temperature of 88 K. The superconductivity was minimally affected by the applied currents and pulsed laser irradiation, demonstrating its remarkable resilience. In addition, residual resistance and a photovoltaic effect were observed, revealing unique electronic properties. Reflectance measurements have highlighted the significant role of superelectrons in the optical response of YBCO. These findings have the potential to facilitate the development of novel and innovative YBCO-based devices, such as light-modulated superconductors and efficient solar cells.

This article describes a method for producing a superconducting composite based on YBCO doped with carbon nanotubes by solid-phase combustion in an atmosphere of pure oxygen. It has been determined that the initial connection of the components, the ignition temperature and holding time, as well as the degree of doping with CNT nanoparticles affect the qualitative and quantitative provision of the superconducting Y123 phase, including its superconducting properties.
