Intraband electronic excitations, phonons, and crystal field transitions of two unique (Nd,Eu,Gd)Ba 2 Cu 3 O y single crystals with different Eu/Gd ratio were studied by Raman spectroscopy. The spectra were measured above and below critical temperatu

Infrared reflectance spectra of the polar optic phonons in a [(BaTiO3)(8)/(SrTiO3)(4)](50) superlattice over the temperature range 8 to 650 K are reported. The spectra exhibit lattice vibration features typical of the perovskite constituents, BaTiO3

Optical properties of Ba 0.75 Sr 0.25 TiO 3 (BST(75/25)) ferroelectric thin film have been investigated by spectroscopic ellipsometry in a broad temperature interval from 10 to 300 K. The polycrystalline perovskite-phase BST films were prepared by pu

Polarized infrared reflectance of ferroelectric [(BaTiO)/(SrTiO)] superlattices grown on DyScO, TbScO, EuScO and SmScOsubstrates by reactive molecular beam epitaxy was measured. Infrared spectra (30–3000 cm) were taken independently from the (110)

Optical properties of PbZr x Ti 1 − x O 3 material have been actively studied in the visible and near band-gap region, but data in the vacuum-ultraviolet spectral region is rather scarce. In this work we focus on well known interband transitions fo
