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 …

We consider mechanisms which can account for the observed rapid decrease of the critical
current density J c (θ) with the misorientation angle θ through grain boundaries (GB's) in …

A systematic study of the weak-link behavior for YBa2Cu3O7− δ polycrystalline samples has
been done using the electrical resistivity and AC susceptibility techniques. The experiments …

The phenomenon of superconductivity has not lost its fascination ever since its discovery in
1911. The flow of electric current without friction amounts to the realization of the old human …

The normal state transport properties of grain boundaries in high-Tc superconductors, of
central importance for a large number of electronic applications, still lack a thorough …

Short review of the topical comprehension of the superconductor materials classes Cuprate
High-Temperature Superconductors, other oxide superconductors, Iron-based …

We identify the intrinsic bulk pairing symmetry for both electron-and hole-doped cuprates
from the existing bulk-and nearly bulk-sensitive experimental results such as magnetic …

Theoretical models are reviewed which describe misfit defect structures at interfaces
(intergrain and interphase boundaries) in nanostructured and polycrystalline films. The …

Although not widely recognized, there is much evidence suggesting that the
superconducting cuprates have an anisotropic s-wave type of gap form, a form which is …

Developing a theory of high-temperature superconductivity in copper oxides is one of the
outstanding problems in physics. It is a challenge that has defeated theoretical physicists for …
