Experimental investigation of electronic interactions in collapsed and uncollapsed LaFe2As2 phases
Ilaria Pallecchi, Elena Stellino, Paolo Postorino +4
The iron-based pnictide LaFe2As2 is not superconducting as-synthesized, but it becomes such below Tc around 12 K upon annealing, as a consequence of a structural transition from a…
Muon spin rotation study of the magnetic penetration depth in the intercalated graphite superconductor CaC6
D. Di Castro, A. Kanigel, A. Maisuradze +9
We report temperature- and magnetic field-dependent bulk muon spin rotation measurements in a c-axis oriented superconductor CaC6 in the mixed state. Using both a simple second mom…
Tuning topological disorder in MgB
D. Di Castro, E. Cappelluti, M. Lavagnini +4
We carried out Raman measurements on neutron-irradiated and Al-doped MgB samples. The irradiation-induced topological disorder causes an unexpected appearance of high frequency…
Role of charge doping and lattice distortions in codoped Mg_{1-x}(AlLi)_{x}B_2 compounds
M. Monni, C. Ferdeghini, P. Manfrinetti +10
We prepared a series of Mg_{1-x}(AlLi)_{x}B_2 samples with 0≤x≤0.45 in order to compensate with Li the electron doping induced by Al. Structural characterization by mea…
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…
Effect of Al doping on the optical phonon spectrum in Mg(1-x)Al(x)B(2)
P. Postorino, A. Congeduti, P. Dore +5
Raman and infrared absorption spectra of Mg(1-x)Al(x)B(2) have been collected for 0<x<0.5 in the spectral range of optical phonons. The x-dependence of the peak frequency, the widt…
