Optical study of the vibrational and dielectric properties of BiMnO3
W. S. Mohamed, A. Nucara, G. Calestani +5
BiMnO3 (BMO), ferromagnetic (FM) below Tc = 100 K, was believed to be also ferroelectric (FE) due to a non-centro-symmetric C2 structure, until diffraction data indicated that its…
Infrared study of the charge-ordered multiferroic LuFe(2)O(4)
F. M. Vitucci, A. Nucara, D. Nicoletti +5
The reflectivity of a large LuFe(2)O(4) single crystal has been measured with the radiation field either perpendicular or parallel to the c axis of its rhombohedral structure, from…
Evolution of a polaron band through the phase diagram of Nd[2-x]Ce[x]CuO[4-y]
S. Lupi, P. Maselli, M. Capizzi +3
The evolution with doping and temperature of the polaronic absorption in a family of high-T superconductors is first followed here across the whole phase diagram. The polaron b…
Infrared absorption from Charge Density Waves in magnetic manganites
P. Calvani, G. De Marzi, P. Dore +5
The infrared absorption of charge density waves coupled to a magnetic background is first observed in two manganites La{1-x}Ca{x}MnO{3} with x = 0.5 and x = 0.67. In both cases a B…
Fano effect in the plane of NdCeCuO: evidence of phonon interaction with a polaronic background
S. Lupi, M. Capizzi, P. Calvani +4
Reflectance measurements in properly selected samples of NdCeCuO with different carrier concentrations provide a firm evidence of Fano antiresonances for…
Optical conductivity of CuO_2 infinite-layer films
P. Dore, P. Calvani, G. De Marzi +5
The infrared conductivity of CaCuO_2, SrCuO_{2-y}, and Sr_{0.85}Nd_{0.15}CuO_2 infinite-layer films is obtained from reflectivity measurements by taking into account the substrate…
