title: Nanostructural characterization of artificial pinning centers in PLD-processed REBa2Cu3O7-δfilms.
abstract: In the context of high temperature superconductors, pulsed laser deposition derived GdBa2Cu3O7-δsample with BaHfO3nanoparticles has been reported to achieve high current density and good IC-B-θ characteristics at high temperatures. Herein, we have carried out a thorough nanostrucural characterization of BaHfO3nanoparticles embedded in GdBCO matrix using scanning transmission electron microscopy, with an emphasis on the dispersion behavior, morphologies and nanostrain, to understand the role of BaHfO3nanoparticles.
