 note = {Critical current density (Jc), irreversibility field (Birr) and microstructure in epitaxial SmBa2Cu3O7-x (SmBCO) films are reported.We have developed a novel approach to deposit high performance Sm1+xBa2-xCu3O6+y (Sm-123) at relatively low substrate temperature on MgO. The use of thin SmBCO seed layer grown at a high substrate temperature enabled us to obtain fully -axis oriented SmBCO films with high critical current density (Jc) of 2.8×10＾5 A/cm2 under 5 T for B//c at 77 K. This value is as high as in the optimized NbTi superconducting wires achieved for 5 T at 4.2 K. Compared with YBa2Cu3O7-y films, Sm-123 films showed higher Jc in high fields at 77 K. Transmission electron microscopy TEM analyses clarified the Sm/Ba composition ratio fluctuations in the Sm-123 matrix composition in the range of x = 0～0.14 with a wavelength of 50～100 nm.},
