Preparation of EuBCO Epitaxial and Textured Films By F-Free Polymer-assisted Chemical Solution Deposition Method

摘要：

　　Epitaxial and textured EuBa2Cu3O7-x(EuBCO) superconductive films were prepared via a F-free polymer-assisted chemical solution deposition (PACSD) method on LaAlO3 (LAO) single crystal substrate in nitrogen atmosphere.Because of the fluorine-free metal organic system,no harmful gas was produced during processing by the PA-CSD method.The film morphorlogy,phase composition,texture and the superconducting critical temperature (Tc) of EuBCO films were investigated by x-ray diffraction(XRD),φ-scan,ω-scan rocking curves,an environmental scanning electron microscope(ESEM) and four-probe method.The Jc value of the EuBCO film in self-field at 77K was measured by using Jc-scan Leipzig system.The results shoed that a denser microstructure and better biaxial texture EuBCO film after a high temperature treatment with a superconducting critical temperature (Tc) of 91K was obtained.The critical current density (Jc) reached 2.4MA/cm2 at 77K in the self-field.
