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…
Magnetoresistance Effects in SrFeO(3-x): Dependence on Phase Composition and Relation to Magnetic and Charge Order
P. Adler, A. Lebon, V. Damljanovic +6
Single crystals of iron(IV) rich oxides SrFeO(3-x) with controlled oxygen content have been studied by Moessbauer spectroscopy, magnetometry, magnetotransport measurements, Raman s…
Charge ordering and magneto-polarons in NaCoO
C. Bernhard, A. V. Boris, N. N. Kovaleva +6
Using spectral ellipsometry, we have measured the dielectric function of a NaCoO crystal that exhibits bulk antiferromagnetism with T=19.8 K. We identify two…
