The isotope effect and phonons in MgB2

The isotope effect and phonons in MgB2

MgB2 shows a large isotope effect coefficient for B and a negligible coefficient for Mg. The total isotope effect is reduced from 0.5, a value that might be expected for a BCS, phonon-mediated, sp superconductor. Recent work reconciling this lower total isotope effect is reviewed with regard to the...

Zusammenfassung:MgB2 shows a large isotope effect coefficient for B and a negligible coefficient for Mg. The total isotope effect is reduced from 0.5, a value that might be expected for a BCS, phonon-mediated, sp superconductor. Recent work reconciling this lower total isotope effect is reviewed with regard to the unique nature of MgB2.
