Pressure and alloying effects on the metal to insulator transition in NiS{2-x}Se{x} studied by infrared spectroscopy
A. Perucchi, C. Marini, M. Valentini +11
The metal to insulator transition in the charge transfer NiS{2-x}Se{x} compound has been investigated through infrared reflectivity. Measurements performed by applying pressure to…
High pressure Raman study of LaCaMnO manganites
A. Sacchetti, T. Corridoni, E. Arcangeletti +1
We report on a high-pressure Raman study on two members of the LaCaMnO manganite family (, and ). The results obtained for the sampl…
Quasiparticle evolution and pseudogap formation in V2O3: An infrared spectroscopy study
L. Baldassarre, A. Perucchi, D. Nicoletti +10
The infrared conductivity of V2O3 is measured in the whole phase diagram. Quasiparticles appear above the Neel temperature TN and eventually disappear further enhancing the tempera…
Electrodynamics near the Metal-to-Insulator Transition in V3O5
L. Baldassarre, A. Perucchi, E. Arcangeletti +5
The electrodynamics near the metal-to-insulator transitions (MIT) induced, in V3O5 single crystals, by both temperature (T) and pressure (P) has been studied by infrared spectrosco…
Raman spectroscopy on cubic and hexagonal SrMnO
A. Sacchetti, M. Baldini, P. Postorino +2
We report on the first optical characterization of both cubic and hexagonal SrMnO. Room-temperature Raman spectra collected by means of a micro-Raman spectrometer are shown. Th…
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…
