Abstract

Combination of extremely fine Gd-211 particles and the LRE/Ba solid solution pinning disorder in a melt processed (Nd0.33Eu 0.33Gd0.33)Ba2Cu3Oy, followed by an optimal oxygenation resulted in outstanding electromagnetic performance of the material. Transmission electron microscopy with energy dispersive X-ray analysis identified nanometer scale Zr-rich NEG-Ba-Cu-O particles. These were evidently responsible for a substantial increase of the critical current density at 77 K and the rise by an order of magnitude at and above 90 K. Efficient field trapping ability at 90.2 K enabled new NEG-123 magnet to be for the first time employed in levitation at liquid oxygen.
