Forming High-Temperature Superconducting Layers at the Interfaces between Nonsuperconducting Phases

Petrov, M. I.; Popkov, S. I.; Terent'ev, K. Yu.; Vasil'ev, A. D. Technical Physics Letters.

An alternative technique for synthesizing high-temperature superconductor samples is proposed, in which superconducting layers should form on the surface of hard-melting Ho2BaCuO5 green phase grains immersed in the liquid phase BaCuO2 + CuO.
