Abstract

Lamination of coated conductor is important to commercialize for electrical stabilizer and mechanical support. It should be known the properties of soldering interface and the variation of superconductivity on coated conductor with various kinds of solders. $SmBa_2Cu_O_x$ thin films were deposited by co-evaporation method (EDDC, Evaporation using Drum in Dual Chambers). 4 kinds of solders were used to investigate interface properties of SmBCO conductors. In-Bi solder could maintain good connection.
