Leggett's plasma resonances and two-gap structures in the CVCs of MgB\(_2\) break junctions \(-\) a direct evidence for a two-gap superconductivity in MgB\(_2\)

In the present investigation (2002) the current-voltage characteristics (CVCs) of break junctions in polycrystalline \(MgB_2\) samples have been studied in the temperature range \(4.2 K < T < T_c\). An inelastic Cooper pair tunneling accompanied by the emission of Leggett plasmons has been fou...
