In previous studies, we found that bulk MgB 2 contained numerous voids in various shapes
and sizes. With the aim of improving the critical current density as well as the mechanical …

The present study focuses on the effects of Ag addition on the critical current density (Jc) and
the mechanical performance of disk‐shaped MgB2 bulk superconductors. MgB2 samples …

The present investigation focuses on methods to further improve the J c values of disk-
shaped bulk MgB 2 superconductors by optimizing the sintering conditions. We prepared …

We fabricated nano-carbon (NC) doped MgB2 bulks using an in situ process in order to
improve the critical current density (Jc) under a high magnetic field and evaluated the …

The present investigation has focused on methods to improve the critical current density (J c)
of the disk-shape bulk MgB 2 superconductor by optimizing sintering conditions. The …

In the present study, La-doped MgB 2 superconductors with different doping levels (Mg 1− x
La x B 2; x= 0.00, 0.01, 0.03 and 0.05) have been synthesized by the solid-state reaction …

MgB 2 bulks with excess Mg addition were rapidly synthesized by sintering at low
temperature in present work. It is found that even after ball milling treatment of original …

Abstract High performance Cu doped MgB 2 bulks were prepared by an in-situ method with
carbon-coated amorphous boron as precursor. It was found that the usage of carbon-coated …

We selected amorphous, nano-size carbon black (10–30nm) as a dopant for MgB2
superconductor to improve critical current density (Jc) at high magnetic field. We fabricated …

The minor Cu (< 3at%) addition could significantly reduce the amount of MgO impurity in the
in situ sintered MgB2 samples and thus improve the critical current density (Jc) at low field …
