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…
Temperature dependence of trapped magnetic field in MgB2 bulk superconductor
R. V. Viznichenko, A. A. Kordyuk, G. Fuchs +4
Based on DC magnetization measurements, the temperature dependencies of the trapped magnetic field have been calculated for two MgB2 samples prepared by two different techniques: t…
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…
Positive influence of ta addition on superconductive properties of high pressure synthesized MgB_2
T. Prikhna, W. Gawalek, N. Novikov +10
Bulk MgB2 - based materials with the following critical current densities (jc) in 1 T field: 570 kA/cm^2 at 10 K, 350 kA/cm^2 at 20 K and 40 kA/cm^2 at 30 K and in 10 T field: 650…
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…
Simple technique for superconducting joints quality estimation in bulk melt-processed high temperature superconductors
A. A. Kordyuk, V. V. Nemoshkalenko, A. I. Plyushchay +2
We propose an empirical approach to estimate the quality of superconducting joints (welds) between blocks of bulk high temperature superconductors (HTS). As a measuring value, we i…
