We report magnetoresistance ( MR) measurements on MgB2 and the corresponding full account from ab initio calculations; we suggest that this combination can be a useful tool to probe electron-phonon coupling. We obtain good quantitative agreement between high-field measurements on neutron-irradiated epitaxial thin films and calculations within...

We studied the upper critical field in poly-crystalline MgB2 samples in which disorder was introduced by different ways: Al substitution and neutron irradiation. We observed that by Al doping critical temperature Tc decreases, the resistivity increases but the upper critical field, Hc2, decreases. This behavior can be explained considering that...

We study the effect of neutron irradiation on the critical current density Jc of isotopically pure polycrystalline Mg 11B2 samples. For fluences in the range 1017–1018 cm−2, Jc is enhanced and its dependence on magnetic field is significantly improved: we demonstrate that, in this regime, pointlike pinning centers are effectively introduced in...
