Pressure dependence of the optical properties of the charge-density-wave compound LaTe$_2$ (2007)
Lavagnini, M., Sacchetti, A., Degiorgi, L., Arcangeletti, E., Baldassarre, L., Postorino, P., ...
We report the pressure dependence of the optical response of LaTe$_2$, which is deep in the charge-density-wave (CDW) ground state even at 300 K. The reflectivity spectrum is collected in the...
Marrocchelli, D, Postorino, P, Di Castro, D, Arcangeletti, E, Dore, P, Guidi, Cestelli M
We report on Raman measurements carried out on $Ca_2FeMoO_6$ and $Sr_2FeMoO_6$ double perovskites as functions of pressure (0–15 GPa) and of temperature (298–370 K). The Raman spectrum of both...
High pressure Raman study of La$_{1-x}$Ca$_x$MnO$_{3-\delta}$ manganites (2007)
Sacchetti, A., Corridoni, T., Arcangeletti, E., Postorino, P.
We report on a high-pressure Raman study on two members of the La$_{1-x}$Ca$_x$MnO$_{3-\delta}$ manganite family ($x=0.20$, $\delta=0$ and $\delta=0.08$). The results obtained for the $\delta=0$...
Electrodynamics near the Metal-to-Insulator Transition in V3O5 (2007)
Baldassarre, L., Perucchi, A., Arcangeletti, E., Nicoletti, D., Di Castro, D., Postorino, P., ...
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 spectroscopy. The T- and...
Marrocchelli, D, Postorino, P, Di Castro, D, Arcangeletti, E, Dore, P, Guidi, Cestelli M
We report on Raman measurements carried out on $Ca_2FeMoO_6$ and $Sr_2FeMoO_6$ double perovskites as functions of pressure (0–15 GPa) and of temperature (298–370 K). The Raman spectrum of both...
Evidence of a pressure-induced metallization process in monoclinic VO$_2$ (2006)
Arcangeletti, E., Baldassarre, L., Di Castro, D., Lupi, S., Malavasi, L., Marini, C., ...
Raman and combined trasmission and reflectivity mid infrared measurements have been carried out on monoclinic VO$_2$ at room temperature over the 0-19 GPa and 0-14 GPa pressure ranges, respectively....
Pressure dependence of the charge-density-wave gap in rare-earth tri-tellurides (2006)
Sacchetti, A., Arcangeletti, E., Perucchi, A., Baldassarre, L., Postorino, P., Lupi, S., ...
We investigate the pressure dependence of the optical properties of CeTe$_3$, which exhibits an incommensurate charge-density-wave (CDW) state already at 300 K. Our data are collected in the...
