Abstract

(Hg,Re)Ba2CaCu2Oy thin films have been fabricated on Ag by reacting laser deposited ReBaCaCuO precursor films with CaHgO2 in sealed quartz tubes. The as-prepared films exhibit excellent phase purity and c-axis texture, characterized by an onset superconducting transition temperature (Tc) of 124 K. The microstructures of the films examined by environmental scanning electron microscope revealed HgRe1212 crystals are plate-like and can grow and connect to each other with different ab-plane orientations. The irreversibility behavior and the temperature dependence of magnetization critical current density Jc, estimated by using Bean's model, are also reported.
