Nanostructural Superconducting Materials for Fault Current Limiters and Cryogenic Electrical Machines
T. A. Prikhna, W. Gawalek, Ya. M. Savchuk +27
Materials of the Y-Ba-Cu-O (melt-textured YBa2Cu3O7-d-based materials or MT-YBCO) and Mg-B-O (MgB2-based materials) systems with high superconducting performance, which can be atta…
High-pressure synthesis of MgB2 with addition of Ti
T. A. Prikhna, W. Gawalek, Ya. M. Savchuk +11
The MgB2 - based material high-pressure synthesized at 2 GPa and 800 C for 1 h from Mg and B (taken in the stoichiometry ratio of MgB2) with addition of 2-10 wt% of Ti demonstrated…
Tracing spatial confinement in semiconductor quantum dots by high-order harmonic generation
H. N. Gopalakrishna, R. Baruah, C. Hünecke +20
We report here on results of experimental-theoretical investigation of high-order harmonic generation (HHG) in layers of CdSe semiconductor quantum dots of different sizes and a re…
Effects of high pressure on the physical properties of MgB2
T. Prikhna, W. Gawalek, Ya. Savchuk +27
The synthesis of MgB2-based materials under high pressure gave the possibility to suppress the evaporation of magnesium and to obtain near theoretically dense nanograined structure…
Inhomogeneity of Magnesium Diboride Structure and its Effect on Critical Current Density
T. Prikhna, W. Gawalek, Ya. Savchuk +19
The influence of the oxygen segregation into Mg-B-O inclusions (which are oxygen enriched as compared to the matrix material) and the formation of boron enriched phases (with near…
Synthesis and Sintering of MgB2 Under High Pressure
T. A. Prikhna, Ya. M. Savchuk, N. V. Sergienko +11
High-pressure (HP) synthesis and sintering are promising methods for manufacturing of the bulk MgB2 superconductive material. The available high-pressure apparatuses with 100 cm3 w…
