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…
Observation of charge-density-wave excitations in manganites
A. Nucara, P. Maselli, P. Calvani +6
In the optical conductivity of four different manganites with commensurate charge order (CO), strong peaks appear in the meV range below the ordering temperature T_{CO}. They are s…
Sub-THz electrodynamics of the graphene-like superconductor CaAlSi
S. Lupi, L. Baldassarre, M. Ortolani +7
We report the first optical study of CaAlSi, a superconductor which displays both the crystal structure of MgB2 and the electronic band structure of intercalated graphites. The ref…
Optical response to magnetic ordering in PrMnO_3: the relevance of the double exchange interaction
R. Sopracase, G. Gruener, C. Autret-Lambert +3
The optical conductivity of the undoped PrMnO manganite has been investigated in details at various temperatures between 300 and 4 K. Its low energy spectrum exhibits an optica…
