抄録: YBa2Cu3Ox (YBCO) films were prepared in nitrous oxide (N2O) gas by pulsed laser ablation (PLA) using Kanthal hot filament of approximately 1000°C for cracking the N2O gas. The crystal orientation was changed from the a-axis to c-axis by turning on the filament. The possible origin of this result is a rise of surface temperature of the substrate by thermal radiation from the hot filament and/or generation of oxygen-related radicals produced by cracking of N2O. Temperature measurements revealed that the change of crystal orientation caused by the hot filament could be partly explained by the substrate heating effect. Mass-analysis revealed that N2O gas was really cracked by the hot filament, supporting the possible change of the crystal orientation by the cracking effect of N2O.
