Influence of aluminum diffusion on MgB2 films grown by hybrid physical–chemical vapor deposition using amorphous aluminum buffers

Results in Physics
This study explores the effect of Al-buffered layers on the crystal structure and superconductivity of MgB2. The unique Mg1-xAlxB2 phase formed at a thickness of 190 nm is a promising technique for thin-film fabrication. The upper critical field (Hc2) of

The Dendritic magnetic avalanches in carbon-free MgB$_2$ thin films with and without a deposited Au layer

, 2005
From the magneto optics images (MOI), the dendritic magnetic avalanche is known to appear dominantly for thin films of the newly discovered MgB$_2$. To clarify the origin of this phenomenon, we studied in detail the MOI of carbon-free MgB$_2$ thin films ...

MgB2 SQUID for Magnetocardiography

, 2012
The discovery of the superconductivity at a transition temperature (TC) of 39 K in magnesium diboride (MgB2) has attracted much attention from many researchers for scientific as well as technical reasons [1]. Compared with Cu-based superconductors (cuprates), MgB2 has lower anisotropy and larger coherence length, in addition to high Tc [2].

Selection of Fe as a barrier for manufacturing low-cost MgB2 multifilament wires – Advanced microscopy study between Fe and B reaction

Journal of Magnesium and Alloys
The high cost of using the niobium (Nb) barrier for manufacturing magnesium diboride (MgB2) mono-and multi-filamentary wires for large-scale applications has become one of the barriers to replacing current commercial niobium-titanium superconductors. The
