Pressure-induced quenching of the charge-density-wave state observed by x-ray diffraction (2008)
Sacchetti, A., Condron, C. L., Gvasaliya, S. N., Pfuner, F., Lavagnini, M., Baldini, M., ...
We report an x-ray diffraction study on the charge-density-wave (CDW) LaTe$_3$ and CeTe$_3$ compounds as a function of pressure. We extract the lattice constants and the CDW modulation wave-vector,...
Lavagnini, M., Sacchetti, A., Marini, C., Valentini, M., Sopracase, R., Perucchi, A., ...
We present new data on the pressure dependence at 300 K of the optical reflectivity of CeTe$_3$, which undergoes a charge-density-wave (CDW) phase transition well above room temperature. The...
Lavagnini, M., Baldini, M., Sacchetti, A., Di Castro, D., Delley, B., Monnier, R., ...
We report on a Raman scattering investigation of the charge-density-wave (CDW), quasi two-dimensional rare-earth tri-tellurides $R$Te$_3$ ($R$= La, Ce, Pr, Nd, Sm, Gd and Dy) at ambient pressure, and...
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...
Optical properties of the Ce and La di-telluride charge density wave compounds (2007)
Lavagnini, M., Sacchetti, A., Degiorgi, L., Shin, K. Y., Fisher, I. R.
The La and Ce di-tellurides LaTe$_2$ and CeTe$_2$ are deep in the charge-density-wave (CDW) ground state even at 300 K. We have collected their electrodynamic response over a broad spectral range...
Tuning topological disorder in MgB$_{2}$ (2006)
Di Castro, D., Cappelluti, E., Lavagnini, M., Sacchetti, A., Palenzona, A., Putti, M., ...
We carried out Raman measurements on neutron-irradiated and Al-doped MgB$_2$ samples. The irradiation-induced topological disorder causes an unexpected appearance of high frequency spectral...
Role of charge doping and lattice distortions in codoped Mg_{1-x}(AlLi)_{x}B_2 compounds (2005)
Monni, M., Ferdeghini, C., Manfrinetti, P., Palenzona, A., Putti, M., Affronte, M., ...
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 means of neutron and...
