New phase transition in system: evidence for electrical polarization in charge ordered manganites
A. M. L. Lopes, J. P. Araujo, V. S. Amaral +3
A detailed study of the electric field gradient (EFG) across the Pr1-xCaxMnO3 phase diagram and its temperature dependence is given. Clearly, distinct EFG behaviours for samples ou…

Percolative phase transition on ferromagnetic insulator manganites: uncorrelated to correlated polaron clusters
A. M. L. Lopes, J. P. Araujo, J. J. Ramasco +5
In this work, we report an atomic scale study on the ferromagnetic insulator manganite LaMnO using PAC spectroscopy. Data analysis reveals a nanoscopic transition fr…
