Dipole-active optical phonons in YTiO_3: ellipsometry study and lattice-dynamics calculations
N. N. Kovaleva, A. V. Boris, L. Capogna +6
The anisotropic complex dielectric response was accurately extracted from spectroscopic ellipsometry measurements at phonon frequencies for the three principal crystallographic dir…

Optical response of ferromagnetic YTiO_3 studied by spectral ellipsometry
N. N. Kovaleva, A. V. Boris, P. Yordanov +8
We have studied the temperature dependence of spectroscopic ellipsometry spectra of an electrically insulating, nearly stoichiometric YTiO_3 single crystal with ferromagnetic Curie…

C-axis lattice dynamics in Bi-based cuprate superconductors
N. N. Kovaleva, A. V. Boris, D. Munzar +8
We present results of a systematic study of the c axis lattice dynamics in single layer Bi2Sr2CuO6 (Bi2201), bilayer Bi2Sr2CaCu2O8 (Bi2212) and trilayer Bi2Sr2Ca2Cu3O10 (Bi2223) cu…
