Growth and Properties of YBa2Cu3O7-x Single Crystals Doped with Rare Earth Oxides

Abstract

The effect of Rare Earth (RE) oxide addition on the crystal growth behavior and superconducting properties of YBa2Cu3O7-x (Y123) was investigated. The results show that even a small amount (< 1 mol%) of RE-oxide addition affects the nucleation and growth kinetics of seeded Y123 crystals. In order to improve the flux pinning capacity of Y123 single crystals, the samples were doped with Nd, Sm, Gd, Er, and Yb oxide. Magnetization measurements on RE-doped Y123 single crystals revealed very high Je values as compared to undoped Y123 single crystals.
