Abstract

In the context of high temperature superconductors, pulsed laser deposition derived GdBa 2 Cu 3 O 7-δ sample with BaHfO 3 nanoparticles has been reported to achieve high current density and good I C -B-θ characteristics at high temperatures. Herein, we have carried out a thorough nanostrucural characterization of BaHfO 3 nanoparticles embedded in GdBCO matrix using scanning transmission electron microscopy, with an emphasis on the dispersion behavior, morphologies and nanostrain, to understand the role of BaHfO 3 nanoparticles.
