 note = {We have reported superconducting properties of Sm1+xBa2-xCu3Oy (SmBCO; x = 0.08) thin films prepared by the low temperature growth technique (LTG). LTG process is consisted of two steps as follows; a seed layer is deposited at 830℃ on MgO(100), and then upper layer is deposited at 740－780℃ on the seed layer. In order to investigate the effect of the fluctuations Sm/Ba composition ratio in the SmBCO matrix, we deposited upper layer with the Sm/Ba composition of x = 0-0.12. The SmBCO films with x = 0.04 and 0.08 show critical current density (Jc) at 77 K of up to 5×10^6 A /cm2 under 0 T and 1×10^5 A /cm2 under 5 T for B//c at 77 K, respectively. The Jc of x = 0.12 film dropped more sharply compared with the cases of x = 0.04 and 0.08 films. From the microstructure analysis, it was found that the main phase of x = 0.12 film was Sm-rich (Sm1.1Ba1.9Cu3Oy) phase, while that of x = 0.04 and 0.08 films was stoichiometry. We speculated that the low-Jc of x = 0.12 film in the magnetic fields was ascribed to the low physical meters of Tc and irreversibility field of the Sm-rich SmBCO main phase.},
