Fabrication and characterization of MgB2/SS 316L superconducting wire with amorphous boron prepared by sintering and cold rolling

Materials Science for Energy Technologies, 2023
Magnesium diboride (MgB2) is proposed to be a highly efficient wire with zero resistivity. In this research, Mg powder and amorphous-boron sheathed with a stainless steel (SS) 316L tube and powder-in-tube (PIT) technique were used in order to create a ...

Theory of fluctuations in a two-band superconductor

, 2004
A theory of fluctuations in two-band superconductor MgB$_{2}$ is developed. Since the standard Ginzburg-Landau (GL) approach fails in description of its properties, we generalize it basing on the microscopic theory of a two-band superconductor ...

MgB₂ Thin Films Fabricated by Pulsed Laser Deposition Using Nd:YAG Laser in an In Situ Two-Step Process

Condensed Matter, 2022
Magnesium diboride (MgB2) thin films on r-cut sapphire (r-Al2O3) single crystals were fabricated by a precursor, which was obtained at room temperature via a pulsed laser deposition (PLD) method using a Nd:YAG laser, and an in situ postannealing process.

Critical Temperature Tc and Charging Energy Ec between B-B layers of Superconducting diboride materials MgB2 in 3D JJA model

, 2001
The diboride materials MB2 (M = Mg, Be, Pb, etc.) are discussed on the basis of the 3D Josephson junction array (JJA) model due to Kawabata-Shenoy-Bishop, in terms of the B-B layers in the diborides analogous to the Cu-O ones in the cuprates.
