Abstract:
High-quality c-axis oriented Bi-2212 thin films have been grown ex situ on single crystal (100) surface of MgO substrates was produced by PLD. The properties of Bi-2212 thin films have been investigated. The films were characterized by SEM, FESEM, X-ray diffraction, resistivity, MVSH, and transport properties. The results show that these films are good quality with c-axis orientation and epitaxial growth, good electrical and magnetic properties .The critical current density Jc was found to be strongly dependent on the temperature and magnetic field. In optimized growth conditions the transport critical current density Jc=6.3×106 A/cm2 in 0.5T magnetic field at 5 K, superconducting transition temperature T c-onset = 95K. and Tc-zero = 75K are obtained.
