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…

Magentically-Induced Lattice Distortions and Ferroelectricity in Magnetoelectric GdMnO3
J. Agostinho Moreira, A. Almeida, J. Oliveira +4
In this work we investigate the magnetic field dependence of Ag octahedra rotation (tilt) and B2g symmetric stretching modes frequency at different temperatures. Our field-dependen…
