The demonstration of the first laser, made with ruby in 1960, 1 has led to a revolution in
science and technology. Lasers have transformed spectroscopy giving previously …

Twenty years ago in a series of amazing discoveries it was found that a large family of
ceramic cuprate materials exhibited superconductivity at temperatures above, and in some …

Crystalline defects on the nano-scale, which are called artificial pinning centers (APCs),
were successfully introduced into high-temperature superconductors (HTS) by …

Addition of pyrochlore rare earth tantalate phases, RE 3 TaO 7 (RTO, where RE= rare earth,
Er, Gd and Yb) to YBa 2 Cu 3 O 7− δ (YBCO) is shown to vastly improve pinning, without …

Raising critical current density J c in high temperature superconductors (HTSs) is an
important strategy towards performance-cost balanced HTS technology for …

BaZrO 3 nanorods are known to be effective pinning centers as c-axis-correlated pinning
centers. Furthermore, BaZrO 3 nanorods in REBa 2 Cu 3 O y (RE: rare-earth element) films …

For use in high-magnetic-field coil-based applications, the critical current density (J c) of
REBa 2 Cu 3 O y (REBCO, where RE= rare earth) coated conductors must be isotropically …

This paper reviews the progress of studies to determine optimum shapes of the artificial
pinning center (APC) of REBa 2 Cu 3 O y thin films and coated conductors towards …

Metal–organic chemical vapor deposition (MOCVD) on flexible, ion beam assisted
deposition MgO templates has been used to produce high critical current density (J c)(Y …

The thickness dependence of the critical current density J c (d) in films due to the two-
dimensional–three-dimensional (2D–3D) pinning crossover at low magnetic fields is …
