These experiments revealed that a reducing environment for the preparation of YBCO films enhances the film growth with the high temperature phase (trilayered perovskite YBCO) rather than the low temperature phase (cubic YBCO). This phenomenon is explained in terms of thermodynamic phase diagram. The effect of nitrous oxide on the thermodynamic phase diagram is far smaller than that of oxygen by a factor of two to three orders of magnitude., 金沢大学設計製造技術研究所 / 金沢大学理工研究域電子情報学系 / 金沢大学工学部}, pages = {963--967}, title = {Low-temperature growth of YBCO thin films by pulsed laser ablation in reducing environment}, volume = {127-129}, year = {1998} }
