Abstract

This paper describes the preparation and characterization of Y Ba₂Cu₃O_7−δfilms using infrared (λ= 1064 nm) Nd:YAG Pulsed Laser Deposition (IR Nd:YAG PLD) with post heat treatment. The as-deposited films have a spheroidal surface morphology. After heat treatment, the film surface contains micron- size rectangular grains. XRD measurement reveals that films are a-axis and c-axis oriented. With oxygen annealing, the films show T_cof about 70 K. The low value T_cis attributed to the granularity of the film and may require appropriate post heat treatment to increase T_c.
