Phase diagram description of the CaCu $_{3}$ Fe $_{4}$ O $_{12}$ double perovskite

Ivon R. Buitrago, C. I. Ventura, R. Allub

CaCu $_{3}$ Fe $_{4}$ O $_{12}$ exhibits a temperature-induced transition from a ferrimagnetic-insulating phase, in which Fe appears charge disproportionated, as Fe $^{3 +}$ and Fe $^{5 +}$ , to…

Mott-Hubbard quantum criticality in paramagnetic CMR pyrochlores

L. Craco, C. I. Ventura, A. N. Yaresko +1

We present a correlated {\it ab initio} description of the paramagnetic phase of Tl $_{2}$ Mn $_{2}$ O $_{7}$ , employing a combined local density approximation (LDA) with multiorbital dynamic…

Magnons in the half-doped manganites

C. I. Ventura, B. Alascio

Recently, based on the refined crystal structure of Pr0.6Ca0.4MnO3 from neutron diffraction, Daoud-Aladine et al.[PRL89,97205(2002)] have proposed a new ground state structure for…
