We fabricated GdBa2Cu3O7-y (GdBCO) films on SrTiO3 single crystalline substrate by metal-organic deposition using trifluoroacetate (TFA). The volume percent of a-axis grains is strongly dependent on the P(H2O). Then, maximum P(H2O) has been changed while heating GdBCO. The higher driving force (high P(H2O)) is required for faster crystallization with growing the GdBCO phase crystals from the substrate, since the volume percent of a-axis grain decreases with increasing the maximum P(H2O). The Tc and the transport Jc values could be obtained as 92 K and 2.3 MA/cm2 at 77 K in self-field.
