Enhanced Jc OF Multi-layer YBa$_{2}$Cu$_{3}$O$_{x}$ Films

ORAL

Abstract

Nd$_{1/3}$Eu$_{1/3}$Gd$_{1/3}$Ba$_{2}$Cu$_{3}$O$_{x}$ (NEG)/YBCO multi-layer up to 6 layer films are made and enhanced $J_{c }$is achieved compared to pure YBCO film. The enhancement is observed over a wide range of temperatures. Possible reason for this enhancement is investigated. Magneto-optical imaging shows that these films have excellent macroscopic magnetic uniformity.
