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…

Polar properties of Eu0.6Y0.4MnO3 ceramics and their magnetic field dependence

J. Agostinho Moreira, A. Almeida, W. S. Ferreira +6

Eu1-xYxMnO3 exhibits, unlike other magnetoelectric systems, very distinctive features. Its magnetoelectric properties is driven by the magnetic spin of the Mn3+ ion, but they can b…
