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…
Higher borides and oxygen-enriched Mg-B-O inclusions as possible pinning centers in nanostructural magnesium diboride and the influence of additives on their formation
Tatiana Prikhna, Wolfgang Gawalek, Yaroslav Savchuk +21
The study of high pressure (2 GPa) synthesized MgB2-based materials allows us to conclude that higher borides (with near MgB12 stoichiometry) and oxygen-enriched Mg-B-O inclusions…
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…
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…
Effect of mesoscopic inhomogeneities on the critical current of bulk melt-textured YBCO
L. S. Uspenskaya, I. G. Naumenko, G. A. Emelchenko +6
The downsizing 211-inclusions and an increase of their density leads to rise in mean critical current value in Y-based melt textured material. Very often 211-inclusion are spread i…
Soldering of MT-YBCO: method to produce superconductive junctions
T. Prikhna, W. Gawalek, N. Novikov +12
A method of soldering of melt-textured YBa2Cu3O7-d -based (MT-YBCO) superconductive blocks using a TmBaCu3O7-d (Tm123) powder has been suggested. The method excludes stages of slow…
