Abstract

Single-layer YBa2Cu3O7-δ (YBCO) films with the thickness of over 600 nm were fabricated by modified metal organic deposition using trifluoroacetate metal organic deposition (TFA-MOD) method on LaAlO3 (LAO) substrates. Polyvinylbutyral (PVB) was added into the precursor solution to enhance the thickness of the single layer. The pyrolysis process was shortened to about 3 h due to the reduction of the fluorine content in the precursor solution. The effects of heating rate during the crystallization process on the microstructure and J c values of YBCO films were investigated. The a-axis-oriented YBCO crystals dominate when the heating rate is lower than 20 °C·min−1, while faster heating rate of 43 °C·min−1 results in pure c-axis epitaxial growth. The J c values of YBCO films increase linearly with heating rate increasing due to the increase of c-axis YBCO growth, and the critical current (I c) value of 100 A·cm−1 within a single-layer YBCO film is achieved.
