REBCOAPL – REBCO masívne supravodiče na báze Y, Gd, Sm a Eu pre praktické aplikácie
Program: SRDA
Project leader: Ing. Diko Pavel, DrSc., akademik US Slovenska
Annotation: The project is focused on research and development of selected REBCO bulk singlegrain superconductors (BSS).We will examine YBCO, GdBCO, SmBCO and EUBCO systems, which are currently preferred in terms ofmastering their production technology and specific applications. Based on our latest results, we will focus on thealloying of LREBCO (LRE- light rare earths) with elements that suppress Ba/LRE substitution in the crystal lattice,the addition of nanocrystalline BaCeO3, the bimodal size distribution of pining centres and the configuration ofholes in REBCO BSS. We will apply the research results in the development of BSS production technology withoptimized superconducting and mechanical properties. The use of the research and development results achievedwithin the project is expected by the manufacturer BSS CAN Superconductors s.r.o.

BULKREBCO – Štruktúra, supravodivé a mechanické vlastnosti masívnych REBCO supravodičov
Structure, superconducting and mechanical properties ov bulk REBCO superconductors
Program: VEGA
Project leader: Ing. Diko Pavel, DrSc., akademik US Slovenska
Annotation: The project is focused on the research of the influence of the structure on the superconducting and mechanical properties of the REBCO bulksingle grain superconductors (BSS). The effect of the bimodal particle size distribution of RE211 particles in the REBCO single crystal will be studied, as well as the effect of alloying. Acquiredthe knowledge will serve to optimize the preparation parameters and structure of REBCO BSS so that they are achievedthe combination of a high value of the trapped magnetic field and levitation force with increased mechanicalstrength. We will use experimental methods of powder metallurgy, bulk single crystal growth, X-ray diffraction, light and electron microstructure analysis, magnetization measurements, measurementsof trapped magnetic field and strength measurement. The project will be solved in cooperation withleading foreign laboratories within the formal (SIT Tokyo, JTU Shanghai, CAN Superconductors) andinformal (University of Cambridge, CRISTMAT Caen, FzÚ Praha, ) cooperation.
