Critical current density, J c, in superconductors is strongly connected with size of defects in
the material. Frequently, the smaller defects, the higher J c. In this work, we tried to reduce …

The improved performance of bulk MgB2 material with added nanometer‐sized MgB4
particles is presented. Bulk polycrystalline MgB2 samples with varying amount of MgB4 x (x …

Silver addition has been known to improve mechanical and superconducting performance of
bulk magnesium boride (MgB2) superconductor synthesized via solid state sintering. While …

Discovery of superconductivity in MgB2[1] attracted research focus from trendy
superconductors (intermetallic,[2] cuprates, etc.). The reason was the specific position of this …

Carbon has been a standard do** agent in MgB2 for long time. It, however, has also
participated in a non‐uniform distribution of the constituents throughout the bulk MgB2. To …

The objective of this review chapter is to improve the flux pinning and critical current density
(Jc) of bulk MgB2 materials for day-today life applications and to highlight the aim of United …

MgB 2 bulk samples with the silver contents of 0, 1.5, 3.0, 4.5, 6.0, 9.0 and 12.0 wt% were
fabricated at 775° C for 3 h in Ar atmosphere by solid-state reaction method. The structural …

MgB2 is a trendy material suitable for several superconductor applications such as bulk
magnets for compact magnetic resonance imaging (MRI) and nuclear magnetic resonance …

The objective of this thesis was to study the ways, how to improve critical current density (Jc)
in polycrystalline magnesium diboride (MgB2) bulk. The superconducting devices demand …
