Abstract

We have fabricated SmBCO coated conductor on IBAD-MgO substrates using unique co-evaporation method. The batch type co-deposition system was specially designed and was named EDDC (evaporation using drum in dual chamber) that is possible to deposit superconducting layer with optimum composition ratio of materials at temperature over 700 °C and several mTorr of oxygen. In this study, we have investigated the influence of SmBCO phase composition ratio on the critical current density of coated conductor. We have optimized the composition ratio by changing the deposition rates of Ba and Cu during co-evaporation for better critical current density. A higher critical current density was measured at the composition ratio of Ba deficiency (1.9-2.0) and Cu rich (3.2-3.4) compared to the Sm₁Ba₂Cu₃O_y stoichiometry. Especially, highest critical current density of 2.6 MA/cm² was measured at the composition of Sm₁Ba_1.9Cu_3.2O_y that has dense surface morphology.
