Abstract

SmBa₂Cu₃O_7-δ(SmBCO) thin films were successfully prepared on the LaAlO₃(100) substrate by the TFA-MOD method in an extremely reduced oxygen atmosphere. The precursor solution was prepared dissolving SmBCO powder into the trifluoroacetic acid solution. The precursor solution was spin-coated on the LaAlO₃(100) single crystalline substrates, calcined at the temperature up to 400°C, and fired at various high temperatures for 2 h in reduced oxygen atmospheres. Optimally processed SmBCO thin film exhibited T_C,zero value of 90.2 K and J_C value of 0.8 MA/cm² at 77 K, respectively. Relatively lower J_C values in SmBCO films compared with MOD-processed YBCO films are attributed to the existence of a-axis oriented grains.
