Abstract
Bi2Sr2CaCu2O8+δ (Bi-2212) superconducting thin films with c-axis epitaxial orientation were prepared on LaAlO3 (LAO) single crystal substrates via a Sol-Gel technique using metallic acetates as starting materials. The influence of the growth temperature and oxygen partial pressure (pO2) on the phase purity and superconducting properties of Bi-2212 was discussed. The results show that Bi-2212 films prepared at 820â¯Â°C with the pO2 of 1.4â¯KPa exhibit good in-plane and out-of-plane growth textures and excellent superconducting properties with high critical transition temperature (Tc) of 88â¯K and narrow transition width (ÎTc) of 4.8â¯K.
