Abstract:
A shaped body of a superconducting material based on (Rare Earth)BaCuO, wherein Rare Earth signifies at least one element selected from the group consisting of Y, La, Ce, Pr, Nd, Eu, Gd, Th, Dy, Ho, Er, Tm, Yb and Lu, and in that the shaped body has a maximum value of remanent induction at 77 K and 0 T of at least 1100 mT, the maximum value of remanent induction obtained by applying a coating material to at least one part of at least one surface of the shaped body, wherein the coating material melts at least partially at a lower temperature than the material of the shaped body, the shaped body and the applied coating material having been heated to a desired temperature at which the material of the shaped body does not yet partially melt but at least partially softens, the applied coating at least partially infiltrating a region near the surface of the shaped body when that region is modified at a temperature at least as high as the desired temperature, and the shaped body being enriched with oxygen to increase at least one of the remanent induction and the critical current density of the shaped body.
