Triple-gap superconductivity of MgB2 - (La,Sr)MnO3 composite. Which of the gaps is proximity induced?

open access: yes, 2011
Interplay of superconductivity and magnetism in a composite prepared of the ferromagnetic half-metallic La_0.67Sr_0.33MnO (LSMO) nanoparticles and the conventional s-wave superconductor MgB_2 has been studied.

Prediction of One‐Dimensional Metallicity and π‐Band Superconductivity in Rhodizonate Radical Pancakes

open access: yesAngewandte Chemie, Volume 137, Issue 47, November 17, 2025.
Equidistant stacking of radicals is typically unstable due to symmetry‐lowering distortions. We predict that such arrangements can be stabilized by multicentered covalent (“pancake”) bonding and Coulombic repulsion between negatively charged radicals.

Josephson effect in MgB_2 break junctions [PDF]

open access: yes, 2001
We present the first observation of the DC and AC Josephson effect in MgB_2 break junctions. The junctions, obtained at 4.2 K in high-quality, high-density polycrystalline metallic MgB_2 samples, show a non-hysteretic DC Josephson effect.

Enhanced critical parameters of nanocarbon doped MgB2 superconductor [PDF]

open access: yesJournal of Applied Physics, 2009
The high field magnetization and magnetotransport measurements are carried out to determine the critical superconducting parameters of MgB2−xCx system. The synthesized samples are pure phase and the lattice parameter evaluation is carried out using the Rietveld refinement. The R−T(H) measurements are done up to a field of 140 kOe.

Ginzburg-Landau theory of vortices in a multi-gap superconductor

open access: yes, 2003
The Ginzburg-Landau functional for a two-gap superconductor is derived within the weak-coupling BCS model. The two-gap Ginzburg-Landau theory is, then, applied to investigate various magnetic properties of MgB2 including an upturn temperature dependence ...

Creating better superconductors by periodic nanopatterning

open access: yesSciPost Physics, 2017
The quest to create superconductors with higher transition temperatures is as old as superconductivity itself. One strategy, popular after the realization that (conventional) superconductivity is mediated by phonons, is to chemically combine different
