Effects of neutron irradiation on polycrystalline Mg11B2
C. Tarantini, H. U. Aebersold, V. Braccini +13
We studied the influence of the disorder introduced in polycrystalline MgB2 samples by neutron irradiation. To circumvent self shielding effects due to the strong interaction betwe…

Observation of the Crossover from Two-Gap to Single-Gap Superconductivity through Specific Heat Measurements in Neutron Irradiated MgB2
M. Putti, M. Affronte, C. Ferdeghini +2
We report specific heat measurements in neutron irradiated MgB2 samples, for which the critical temperature has been suppressed down to 8.5 K, but the superconducting transition re…

Neutron Irradiation of Mg11B2 : From the Enhancement to the Suppression of Superconducting Properties
M. Putti, V. Braccini, C. Ferdeghini +9
In this letter we present the effect of neutron irradiation up to fluences of 3.9 1019 n/cm2 on the superconducting properties of MgB2. In order to obtain a disorder structure homo…
