In order to improve a critical temperature (T_c) of LaBa₂Cu₃O_y (LaBCO) thin films for achieving a high irreversibility field, we investigated the vapor-liquid-solid (VLS) technique with various composition ratios of Ba/Cu in a liquid layer as growth solvent. As a result, we achieved the VLS-LaBCO thin films with excellent crystallinity and observed a spiral growth consisted of the wide terrace with a width of about 300 nm. Moreover, the orthorhombicity and the T_c onset of VLS-LaBCO thin films increased with increasing Ba/Cu ratio in the liquid layer.
