Unusual giant magnetostriction in the ferrimagnet GdCaMnO
V. F. Correa, N. Haberkorn, G. Nieva +2
We report an unusual giant linear magnetostrictive effect in the ferrimagnet GdCaMnO (80 K). Remarkably, the magnetostriction, negative at high t…
Coexisting on- and off-center Yb3+ sites in Ce1-xYbxFe4P12 skutterudites
F. A. Garcia, D. J. Garcia, M. A. Avila +8
Electron Spin Resonance (ESR) measurements performed on the filled skutterudite system Ce1-x$YbxFe4P12 (x< 0.003) unequivocally reveal the coexistence of two Yb3+ resonances, assoc…
The effect of Coulomb interaction at ferromagnetic-paramagnetic metallic perovskite junctions
R. Allub, J. D. Fuhr, M. Avignon +1
We study the effect of Coulomb interactions in transition metal oxides junctions. In this paper we analyze charge transfer at the interface of a three layer ferromagnetic-paramagne…
Pressure induced Insulator-Metal transition in LaMnO
Javier D. Fuhr, Blas Alascio, Michel Avignon
The recent observation of a insulator to metal transition (IMT) [I. Loa et al, PRL 87, 125501 (2001)] in pure LaMnO at 32 GPa and room temperature, well above the Neel temperat…
Spin order in the one-dimensional Kondo and Hund lattices
D. J. Garcia, K. Hallberg, B. Alascio +1
We study numerically the one-dimensional Kondo and Hund lattices consisting of localized spins interacting antiferro or ferromagnetically with the itinerant electrons, respectively…
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…
