Undoped and WO3-doped Y-Ba-Cu-O ceramics have been slowly cooled in flowing oxygen or quenched in air from 900°C to room temperature, after sintering at 900°C for 30h in flowing oxygen. The ac susceptibility measurements show that the Tc of the que

Undoped and WO3-doped Y-Ba-Cu-O ceramics have been studied by Raman spectroscopy. The results show that the peak positions at 499 and 338 cm-1 have been shifted for WO3-doped samples compared with those for undoped samples, which reveals that the oxy

The phase formation of the samples with the norminal composition (Y1-xCex)Ba2Cu3O7-δ(x = 0,0.05,0.1, 0.3, 0.55,1.0)has been studied by Raman spectroscopy. It is found that the impurity phases of BaCeO3 and BaCuO2 have been formed with Ce doping, bes
