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…
Competing exchanges and spin-phonon coupling in Eu1-xRxMnO3 (R=Y,Lu)
D. A. Mota, Y. Romaguera Barcelay, P. B. Tavares +5
This work is focused on the phase diagrams and physical properties of Y-doped and Lu-doped EuMnO3. The differences in the corresponding phase boundaries in the (x,T) phase diagram…
Structural and insulator-to-metal phase transition at 50 GPa in GdMnO3
J. Agostinho Moreira, A. Almeida, J. Oliveira +6
We present a study of the effect of very high pressure on the orthorhombic perovskite GdMnO3 by Raman spectroscopy and synchrotron x-ray diffraction up to 53.2 GPa. The experimenta…
THz and infrared studies of multiferroic hexagonal Y_(1-x)Eu_xMnO_3 (x=0 - 0.2) ceramics
V. Goian, S. Kamba, C. Kadlec +5
We report an investigation of hexagonal Y_(1-x)Eu_xMnO_3 ceramics with x=0, 0.1 and 0.2 using infrared and THz spectroscopies in the temperature range between 5 and 900 K. The temp…
Strong magneto-elastic coupling and polar properties in orthorhombic Eu1-xYxMnO3 manganite
J. Agostinho Moreira, A. Almeida, W. S. Ferreira +8
This work reports an experimental investigation of the magneto-elastic coupling and polarization character of magnetic phases of the orthorhombic Eu1-xYxMnO3 system at low temperat…
Coupling between phonons and magnetic excitations in orthorhombic Eu_{1-x}Y_xMnO_3
J. Agostinho Moreira, A. Almeida, W. S. Ferreira +4
In this work we present a detailed study of the structural and lattice dynamic properties of Y-doped EuMnO3 ceramics (Eu1-xYxMnO3, with 0<x<0.55). A thorough analysis towards the c…
