Active nematic-isotropic interfaces on flat surfaces: effects of anchoring, ordering field and activity
Rodrigo C. V. Coelho, José A. Moreira, Duarte M. C. Pedro +1
A surface in contact with the isotropic phase of a passive liquid crystal can induce nematic order over distances that range from microscopic to macroscopic when the nematic-isotro…
Two Displacive Ferroelectric Phase Transitions in Multiferroic Quadruple Perovskite
A. Maia, M. Kempa, V. Bovtun +6
We report on the microwave, terahertz (THz), infrared and Raman spectroscopic studies of ceramics, shedding more light into the nature of two structural phase tran…
Modifying the magnetoelectric coupling in TbMnO by low-level Fe substitution
A. Maia, R. Vilarinho, C. Kadlec +6
We report a comprehensive study of the low-level substitution of Mn by Fe effect on the static and dynamic magnetoelectric coupling in TbMnFeO (,…
Crossover in the pressure evolution of elementary distortions in RFeO3 perovskites and its impact on their phase transition
R. Vilarinho, P. Bouvier, M. Guennou +9
This work reports on the pressure dependence of the octahedra tilts and mean Fe-O bond lengths in RFeO3 (R=Nd, Sm, Eu, Gd, Tb and Dy), determined through synchrotron X-ray diffract…
Raman spectroscopy of rare-earth orthoferrites RFeO3 (R = La, Sm, Eu, Gd, Tb, Dy)
Mads Christof Weber, Mael Guennou, Hong Jian Zhao +5
We report a Raman scattering study of six rare earth orthoferrites RFeO3, with R = La, Sm, Eu, Gd, Tb, Dy. The use of extensive polarized Raman scattering of SmFeO3 and first-princ…
Structural properties and spin-phonon coupling in orthorhombic Y-substituted GdMnO
R. Vilarinho, E. C. Queirós, A. Almeida +2
We present a systematic study of the structure and lattice dynamics at room temperature, and the phonon behavior at low temperatures in orthorhombic GdYMnO mang…
