Abstract

We have investigated the superconducting properties and the microstructure of c-axis oriented Sm_1+xBa_2-xCu₃O_6+y (SmBCO) thin films deposited on MgO substrates by pulsed laser deposition (PLD). In particularly, the use of thin c-axis oriented seed layer grown at high temperature enabled us to obtain fully c-axis oriented SmBCO films at relatively low temperature (∼740 °C). The values of T_c for the present films are within the range of 91.5-92.5 K. From their J _c-B characteristics, it has been observed that the superconducting properties of SmBCO (x = 0.04, 0.08) films are superior to those of the YBa ₂Cu₃O_7-y thin films for B∥c, 5 T at 77 K. The J_c values of the SmBCO films measuring 2.8 × 10⁵ A/m² for 5 T of B∥c at 77 K are comparable to that of NbTi for 5 T at 4.2 K. Furthermore, the superconducting properties in SmBCO change with the substitution of Sm-Ba. The Electron microscopic studies with EDX and S-TEM analysis have revealed that the Sm/Ba ratio fluctuates within the range of x = 0-0.14 with a wavelength of ∼100 nm. High-J_c values in high magnetic fields at 77 K demonstrate the potential of REBCO films for high-field applications of oxide superconductor.
