Magnetic superspace groups and symmetry constraints in incommensurate magnetic phases
J. M. Perez-Mato, J. L. Ribeiro, V. Petricek +1
Although superspace formalism has become the standard approach for the analysis of structurally modulated crystals, it has remained during the last thirty years almost unexplored a…
Landau model for the phase diagrams of the orthorhombic rare-earth manganites RMnO3
J. L. Ribeiro, L. G. Vieira
The present work aims to describe, within a single phenomenological approach, the specific sequence of phase transitions observed in the rare-earth manganites RMnO3 at zero magneti…
Symmetry, incommensurate magnetism and ferroelectricity: the case of the rare-earth manganites RMnO3
J. L. Ribeiro
The complete irreducible co-representations of the paramagnetic space group provide a simple and direct path to explore the symmetry restrictions of magnetically driven ferroelectr…
On the magnetically driven ferroelectric phase in GdMnO3
J. L. Ribeiro
At room temperature, GdMnO3 is a paraelectric and paramagnetic with a distorted perovskite structure of orthorhombic symmetry (space group Pnma). On cooling, it undergoes a phase t…
Symmetry and magnetically driven ferroelectricity in rare-earth manganites RMnO3 (R=Gd, Tb, Dy)
J. L. Ribeiro
This work investigates the magnetically driven ferroelectricity in orthorhombic manganites RMnO3 (R=Gd, Dy or Tb) from the point of view of the symmetry. The method adopted general…
