More discussion from the theory is suggested
Magnetic-field induced effects on the electric polarization in RMnO3 (R = Dy, Gd)
R. Feyerherm, E. Dudzik, A. U. B. Wolter +8
X-ray resonant magnetic scattering studies of rare earth magnetic ordering were performed on perovskite manganites RMnO3 (R = Dy, Gd) in an applied magnetic field. The data reveal…
Ferromagnetism and Lattice Distortions in the Perovskite YTiO
W. Knafo, C. Meingast, H. v. Löhneysen +7
The thermodynamic properties of the ferromagnetic perovskite YTiO are investigated by thermal expansion, magnetostriction, specific heat, and magnetization measurements. The lo…
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…
Coupling of frustrated Ising spins to magnetic cycloid in multiferroic TbMnO3
O. Prokhnenko, R. Feyerherm, M. Mostovoy +5
We report on diffraction measurements on multiferroic TbMnO3 which demonstrate that the Tb- and Mn-magnetic orders are coupled below the ferroelectric transition TFE = 28 K. For T…
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…
