Among the light rare earth (LRE)Ba2Cu3Oy (LRE elements: Nd, Sm, Eu and Gd) family, in which LRE site is compounded with three different elements, only (Nd0.33Eu0.33Sm0.33)Ba2Cu3Oy (NES123) exhibits poor flux pinning properties along with a broad superconducting transition. However, when Y is added to NES123, the sample exhibits high Jc values and a sharp superconducting transition Tc. The flux distribution of NES123 with magneto-optical (MO) observations revealed that the NES123 sample is not a single domain, while the Y added NES123 exhibits single grain feature. Thus, poor superconducting properties are not inherent to the NES123 system and dependent on processing conditions. In fact, the superconducting properties of NSE123 were dramatically improved by using melt-quenched powders as precursor. The Jc(B) curves derived from magnetization loops exhibited a strongly developed peak effect for the melt-quenched NSE123.
