Abstract

High magnetization bulk YBaCuO superconductor was synthesized using Quasi-Melt-Process. The extent of magnetization was dependent on the composition of initial powder mixture, and the magnetization of Y{sub 1}Ba{sub 1.8}Cu{sub 3}O{sub y} and Y{sub 1.2}Ba{sub 2.1}Cu{sub 3.1}O{sub x} (123 + 10%211) was twice than that of Y{sub l}Ba{sub l.8}Cu{sub 3}O{sub y}. Anomalous double peak was observed in the M-H curve of Y{sub 1}Ba{sub 1.8}Cu{sub 3}O{sub y} and Y{sub l.2}Ba{sub 2.1}Cu{sub 3.1}O{sub x} (123 + 10%211) specimen. YBaCuO superconducting thin film with a Tc of 81K has been prepared on (100) MgO single crystal substrate by CVD method. The crystallographic nature and R-T characteristics were hardly affected by the pressure change of reaction tube. However, the microstructure of the film was greatly affected: the film thickness increased three times when the pressure of the reaction tube was reduced from 20 to 5 torr. (Author).
