Even before it was identified as a science and given a name, nanotechnology was the
province of the most innovative inventors. In medieval times, craftsmen, ingeniously …

Improved trapped fields are reported for bulk melt-textured YBa 2 Cu 3 O 7− δ (YBCO)
material in the temperature range between 20 and 50 K. Trapped fields up to 12.2 T were …

This paper reviews recent advances in the melt process of (RE)–Ba–Cu–O [(RE) BCO,
where RE represents a rare earth element] single grain high-temperature superconductors …

The magnitude of the maximum trapped magnetic field in a bulk, single-grain
superconductor is a key performance figure of merit. This is determined, generally, by the …

Superconductors is neither about basic aspects of superconductivity nor about its
applications, but its mainstay is superconducting materials. Unusual and unconventional …

A series of YBa2Cu3Oy (YBCO) samples with small amounts (0–0.6 wt.%) of nanosized
alumina particles (50nm) are synthesized in air by solid state reaction. The microstructure …

Effects of dilute impurity doping to the CuO chain of Y123 on the flux pinning properties were
studied using single crystals and melt-solidified bulks. Cobalt-doped Y123 single crystals …

Large single-grain bulk RE–Ba–Cu–O (RE: rare earth elements) superconductors with high
Jc values can trap magnetic fields much greater than conventional permanent magnets. At …

The effects of Pr-doping on the critical current density Jc and the critical temperature Tc in
YBa2Cu3O7− δ (YBCO) have been investigated. In spite of the monotonic decrease in Tc …

Magnetic properties of melt-processed YBCO doped with different content of Li, Ni and Pd
impurities are reported. The increase of critical currents of doped materials has been …
