Abstract

Superconducting Yttrium-doped Bi₂Sr₂CaCu₂O_8+δ films were synthesized by infrared 1064 nm Nd:YAG pulsed laser deposition with post heat treatment. The influence of Y on the growth as well as the superconducting properties was studied. Smooth and plate-like features with spheroidal particulates were observed on the surface of pure and doped films. The c-axis orientation of the film was retained while the c-lattice parameters were reduced with Y addition. The onset of superconductivity is enhanced with increasing Y doping up to 93 K for x=0.02 but dropped with continuous doping.
