Abstract

Microstructures of BaZrO3 (BZP) doped as artificial pinning centers in ErBa2Cu3O7-δ (ErBCO) films were studied by high-resolution transmission electron microscopy (HR-TEM). BZP-doped ErBCP films were grown by a pulsed laser deposition (PLD) method. In the HR-TEM observation, the presence of nanorods with 10nm average diameter was confirmed from Moiré fringe analysis. The lattice constant of nanorods in the ErBCP was measured using a selected area electron diffraction pattern (SAEDP) as 0.416 nm, which was in good agreement with the lattice constant of BZP, 0.419 nm, provided by X-ray diffraction data. Moiré fringes were observed in both cross-sectional-view and plan-view of the HR-TEM images. The distances of the Moiré fringes were 2.07, 3.22, and 3.05 nm, and which corresponded to the 200, 006, and 110 reflections of the ErBCP matrix and the 200, 002, and 110 reflections of nanorods, respectively. It is suggested that BZO disperses in ErBCO film as nanorods.
