Abstract

BaMO3 (M = Hf, Sn)-doped Sm1+xBa2-xCu3Oy (x= 0, 0.04) superconducting films were fabricated by pulsed-laser deposition (PLD). It is known that BaMO3 nanorods are formed in superconducting films and that the morphology of nanorods affects the superconducting properties, particularly the critical current density ( JC) properties. In this study, superconducting films were fabricated by conventional PLD and by PLD using a low-temperature growth technique to control the morphology of the nanorods. The relationship between the nanorod morphology and JC properties is discussed.
