Description
We report superconducting properties and microstructures of a ErBa2Cu3O7-δ (ErBCO) film with 1.5 wt% BaNb2O6 (BNO) grown by pulse laser deposition (PLD) on a SrTiO3 (STO) substrate. The BNO was introduced into the ErBCO film as an artificial pinning center. Nano-rods originated in the BNO-doping and some particulate defects were clearly observed in transmission electron microscopy (TEM) images of the ErBCO film. The ErBCO film with BNO-doping (BNO + ErBCO) had almost the same critical temperature (TC) as that of a pure ErBCO film. On the other hand, the BNO + ErBCO film showed less critical current density (JC) than that of the pure ErBCO film. The angular peaks for H-parallel c-axis on JC-B-θ curves were not confirmed under all the measured external magnetic fields. X-ray diffraction analysis indicated the high orientation to the both c-axis and in-plane for the obtained film. However, the low surface flatness was confirmed by the TEM and atomic force microscopy (AFM) observation
