Upper critical field and fluctuation conductivity in the critical regime of doped SmFeAsO
I. Pallecchi, C. Fanciulli, M. Tropeano +7
We measure magnetotransport of F doped SmFeAsO samples up to 28T and we extract the upper critical fields, using different criteria. In order to circumvent the problem of criterion…
Two-band parallel conductivity at terahertz frequencies in the superconducting state of MgB.
M. Ortolani, P. Dore, D. Di Castro +7
The optical response of the two-band superconductor MgB has been studied in the 0.7-4 THz range on films with very low impurity level. The effect of the high-energy -gap is…
Probing the electron-phonon coupling in MgB2 through magnetoresistance measurements in neutron irradiated thin films
M. Monni, I. Pallecchi, C. Ferdeghini +9
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…
Effect of the four-sheet Fermi surface on magnetoresistivity of MgB2
I. Pallecchi, M. Monni, C. Ferdeghini +4
Recent experimental data of anisotropic magnetoresistivity measured in MgB2 films have shown an intriguing behaviour: the angular dependence of magnetoresistivity changes dramatica…
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…
Clean and Dirty Superconductivity in Pure, Al doped, and Neutron Irradiated MgB2: a Far-Infrared Study
M. Ortolani, D. Di Castro, P. Postorino +4
The effects of Al substitution and neutron irradiation on the conduction regime (clean or dirty) of the - and -band of MgB have been investigated by means of far-infrar…
