Superconductivity in MgB2 and Alloys
Superconductivity in MgB2 and Alloys is a research topic within Condensed Matter Physics. Science Explorer counts 15k research works in it since 1950. 16.4% of them reached the world's top 10% most cited for their field and year.
This cluster of papers explores the superconducting properties of magnesium diboride (MgB2), including its high transition temperature, multiple energy gaps, anharmonicity, critical current density enhancement, two-band superconductivity, electron-phonon coupling, isotope effects, and nanostructure doping. The research also investigates the behavior of MgB2 in high magnetic fields.
