English abstract:
In addition to the well investigated YBa2Cu3O7-δ(Y-123, YBCO) compound, many other rare earth-123
compounds are candidate materials for the production of coated conductors. Sm-123 seems to be an
excellent alternative because of its higher transition temperature (Tc) and higher critical current densities
(Jc) in external magnetic fields. Because of the fast decrease of Jc in YBCO at elevated temperatures, especially
around the boiling point of liquid nitrogen, the slightly higher Tc can be an important advantage.
Recently, significant progress has been made in the production of long length Sm-123 based coated conductors.
We report here on transport measurements on these conductors in the liquid nitrogen temperature
range. The critical current densities were determined as a function of the applied field and the
crystallographic orientation under maximum Lorentz force configuration. A shift of the c-axis (~7) from
the tape normal was found. The conductor properties were compared to those of commercially available
YBCO coated conductors. The critical current densities as well as the irreversibility fields are higher in the
SmBCO tapes, thus demonstrating the superior properties of the Sm-123 compound.
