Since the first days of high-T c superconductivity, the materials science and the physics of
grain boundaries in superconducting compounds have developed into fascinating fields of …

In the past few years magneto-optical flux imaging (MOI) has come to take an increasing role
in the investigation and understanding of critical current densities in high-T c …

Over the past ten years the perception of grain boundaries in YBa 2 Cu 3 O 7− δ conductors
has changed greatly. They are now not a problem to be eliminated, but an inevitable and …

Coupled magneto-optical imaging and local misorientation angle mapping have been used
to demonstrate the percolative nature of supercurrent flow in YBa2Cu3O7x YBCO coated …

Abstract YBa 2 Cu 3 O 7/YSZ/C e O 2 heterostructures have been grown epitaxially on
biaxially textured Ni substrates by pulsed laser deposition. The texture of the film was …

We investigate the description of current transfer in polycrystalline superconductors by
percolation theory and its limitations. Various computer models that have been proposed are …

We present a complete description of a noninvasive inductive methodology developed to
study the magnetic granularity inherent in coated conductors. The method is based on the …

Surface and bulk texture measurements have been carried out on highly aligned NiFe tapes,
suitable for use as coated conductor substrates. Data from small-area electron backscatter …

We have performed voltage–current V–I measurements on a thin film YBa2Cu3O7 4 001 tilt
low-angle grain boundary over an extensive range of temperatures and fields, verifying the …

The grain boundary networks of tetragonal and orthorhombic superconductors are shown to
be nonrandom through computer simulations of polycrystalline structures. For biaxially …
