Experimental confirmation of the low B isotope coefficient in MgB2
P. Brotto, M. Tropeano, C. Ferdeghini +4
Recent investigations have shown that the first proposed explanations of the disagreement between experimental and theoretical value of isotope coefficient in MgB2 need to be recon…
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 Al-Doped MgB2 Samples: Correlation with the Suppression of Sigma-Band Gap
M. Putti, C. Ferdeghini, M. Monni +7
In this Letter, the study of the effect of Al substitution on the upper critical field, Bc2, in AlxMg1-xB2 samples is presented. We find a straightforward correlation between Bc2 a…
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…
Two-band effects in transport properties of MgB2
M. Putti, V. Braccini, E. Galleani +5
We present resistivity and thermal conductivity measurements on bulk samples, prepared either by a standard method or by a one-step technique. The latter samples, due to their high…
Transport properties of MgB2
M. Putti, E. Galleani d'Agliano, D. Marre +4
In this paper we present the resistivity, the Seebeck effect, and the thermal conductivity measurements on a MgB2 sintered sample. Such transport properties highlight the role of t…
