2024年3月1日 · In this manuscript, the state-of-the-art manufacturing and challenges associated with superconducting MgB 2 tapes, wires, and bulks for a multitude of applications are explained.

2001年3月1日 · Here we report the discovery of bulk superconductivity in magnesium diboride, MgB 2. Magnetization and resistivity measurements establish a transition temperature of 39 K, which we believe to...

2002年8月15日 · Here we report an ab initio calculation of the superconducting gaps in MgB 2 and their effects on measurable quantities. An important feature is that the electronic states dominated by orbitals...

2001年11月5日 · This review paper illustrates the main normal and superconducting state properties of magnesium diboride, a material known since the early 1950s but only recently discovered to be superconductive at a remarkably high critical temperature Tc = 40 K for a binary compound. What makes MgB 2 so special?

2019年5月3日 · Here, we discover the existence of a topological phase in a conventional SC of MgB 2 with a Tc of ~40 K, the highest transition temperature known for a bulk BCS SC.

MgB2 is hexagonal omega structure structured and crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional. Mg is bonded to twelve equivalent B atoms to form a mixture of edge and face-sharing MgB12 cuboctahedra. All Mg–B bond lengths are 2.50 Å.

2021年12月27日 · In this review, synthesis methods of MgB 2, the effect of alloying and thermomechanical treatment on the structure and properties of MgB 2, and production methods for MgB 2 -based wires are considered. Prospects of application of MgB 2 -based wires and cables for power lines are also discussed.

2003年3月1日 · All of the data presented in this paper comes from measurements of polycrystalline samples of MgB 2. Two basic types of samples were used: sintered pellets and wire segments. Both types of samples were synthesized by …

2007年10月15日 · Flux pinning is very weak in MgB 2 single crystals and was only improved by irradiation techniques so far. In polycrystalline samples, grain boundary pinning seems to play the dominant role. High critical currents close to the theoretical limit were found in c …

2024年9月24日 · Magnesium diboride (MgB 2), known for its highest transition temperature (Tc = 39 K) among metallic superconductors, is a viable material for elevated temperature and higher frequency superconducting devices moving toward THz frequencies.
