The superconducting properties of directionally solidified YBa 2 Cu 3 O 7-Y 2 BaCuO 5
composites, with critical currents above 10 5 A/cm 2 at 77 K and zero magnetic field, are …

The complex microstructure of directionally solidified YBa 2 Cu 3 O 7− Y 2 BaCuO 5
composites having up to 30 vol% 2: 1: 1 precipitates with sizes down to 0.1 μm and critical …

Direct transport measurements of the angular dependencies of the critical current density for
single-crystalline and melt-textured YBa 2 Cu 3 O 7− δ have been carried out in the …

Medium-fluence fast electron irradiation (1019 e/cm2 to 1020 e/cm2) or the changes in the
praseodymium concentration in the range of 0.0≤ z≤ 0.5 on the excess conductivity of …

Two PMP-processed YBCO specimens fabricated at different melting temperatures were
investigated. The critical current density (J c) was determined from flux-profile …

[en] The effects of annealing on the transverse resistivity of YBa 2 Cu 3 O 7–δ single crystals
irradiated with high-energy electrons were studied. It is established that annealing led to a …

TEM studies have been conducted on melt-textured YBa2Cu3Ox samples that were
uniaxially and isostatically deformed at high temperatures and compared with those of …

In the present study, dense pellets of polycrystalline YBa 2 Cu 3 O 7− δ were made by
dynamic powder compaction. The shock wave, which passes through the initially loose …

In this work, we studied the fixation of magnetic vortices (pinning effect) on “inelastic” and
“elastic” twins, whose wedge-shaped peaks in the direction of twinning do not reach the …

In our previous work we showed that gradients of temperature T inside the heating chamber
and∂ T/∂ t are the necessary conditions for growing oriented crystal layers inside bulk …
