Magnetoresistivity in MgB2 as a probe of disorder in p- and s-bands
I. Pallecchi, V. Ferrando, E. Galleani D'Agliano +10
In this paper we present normal state magnetoresistivity data of magnesium diboride epitaxial thin films with different levels of disorder, measured at 42K in magnetic fields up to…

Enhanced flux pinning in neutron irradiated MgB2
I. Pallecchi, C. Tarantini, H. U. Aebersold +11
We study the effect of neutron irradiation on the critical current density Jc of isotopically pure polycrystalline Mg11B2 samples. For fluences in the range 1017-1018 cm-2, Jc is e…

Critical Field of MGB2 : Crossover from Clean to Dirty Regimes
M. Putti, V. Braccini, C. Ferdeghini +5
We have studied the upper critical field, Bc2, in poly-crystalline MgB2 samples in which disorder was varied in a controlled way to carry selectively p and s bands from clean to di…
