Abstract

We have grown a-axis oriented ErBa2Cu3O 7-δ (ErBCO) films. Crystallinity of ErBCO films grown on Gd2CuO4 (GCO) buffer layers are investigated at various growth temperatures, in order to find a condition to fabricate a-axis oriented ErBCO films. a-Axis oriented ErBCO films are also grown at a high growth substrate temperature by using YBa2Cu3O 7-δ (YBCO)/GCO double buffer layers. We have successfully fabricated a-axis oriented ErBCO films with the GCO buffer layer by optimizing the substrate temperature during growth. Furthermore, we optimized growth temperatures for a-axis oriented ErBCO films are increased by using the YBCO/GCO buffer layer.
