Abstract
We have investigated the superconducting properties and surface morphology of $Sm_xBa_yCu_3O_{6+z}$ thin films deposited on LMO/IBAD-MgO/Hastelloy which prepared with different composition ratio by co-evaporation method(EDDC, Evaporation using Drum in Dual Chambers). We observed the composition ratio of SmBCO thin films by EDS analysis. We fabricated SmBCO thin film with critical current density of $1.5{\times}10^6A/cm^2$ at composition ratio of SM:Ba:Cu=1.10:2.01:3(at 77 K self-field). And, we confirmed that substitution of Sm-Ba did not occur at Cu rich phase by EDS analysis.
