Pressure dependence of the single particle excitation in the charge-density-wave CeTe system
M. Lavagnini, A. Sacchetti, C. Marini +8
We present new data on the pressure dependence at 300 K of the optical reflectivity of CeTe, which undergoes a charge-density-wave (CDW) phase transition well above room temper…
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…
The optical phonon spectrum of SmFeAsO
C. Marini, C. Mirri, G. Profeta +12
We measured the Raman and the Infrared phonon spectrum of SmFeAsO polycrystalline samples. We also performed Density Functional Theory calculations within the pseudopotential appro…
Transport and infrared properties of SmFeAs(O1-xFx): from SDW to superconducting ordering
M. Tropeano, C. Fanciulli, C. Ferdeghini +12
We report measurements of resistivity, magnetoresistivity, Hall effect, Seebeck coefficient, infrared reflectivity of undoped SmFeAsO and lightly doped SmFeAs(O0.93F0.07) oxypnicti…
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…
