Dynamic and structural properties of orthorhombic rare-earth manganites under high pressure
D. A. Mota, A. Almeida, V. H. Rodrigues +6
We report a high-pressure study of orthorhombic rare-earth manganites AMnO3 using Raman scattering (for A = Pr, Nd, Sm, Eu, Tb and Dy) and synchrotron X-ray diffraction (for A = Pr…

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…

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…
