Superconducting magnets have a variety of industrial, medical and research applications.
This review discusses the prospects for MgB 2 superconductor for practical magnet …

An overview of the theory of the upper critical field in dirty two-gap superconductors, with a
particular emphasis on MgB2 is given. We focus here on the maximum Hc2 which may be …

Doping of MgB 2 by nano-SiC and its potential for the improvement of flux pinning were
studied for MgB 2− x (SiC) x/2 with x= 0, 0.2, and 0.3 and for 10 wt% nano-SiC-doped MgB 2 …

We report a significant enhancement of the upper critical field H c2 of different MgB 2
samples alloyed with nonmagnetic impurities. By studying films and bulk polycrystals with …

An overview of the current state of development of MgB2 wires and tapes prepared by
several techniques is presented, based on the known literature data and our own results …

In spite of the relatively short time dedicated to the development of magnesium diboride
conductors since its discovery in early 2001, a substantial improvement was soon achieved …

Although the fascinating effect of superconductivity was discovered more than 100 years
ago, only a few low-temperature superconductors, especially Nb 3 Sn and NbTi, have …

Nanocarbon-doped Fe-sheathed Mg B 2 tapes with different doping levels were prepared by
the in situ powder-in-tube method. Compared to the undoped tapes, J c for all the C-doped …

A key issue affecting the critical current density of MgB 2 is the lack of full electrical
connectivity. In situ MgB 2 wires can be easily fabricated by reacting Mg powder with …

By doping MgB 2 superconductor with SiC nano-particles, we have successfully introduced
pinning sites directly into the crystal lattice of MgB 2 grains (intra-grain pinning). It became …
