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…
High temperature susceptibility in electron doped Ca1-xYxMnO3: Double Exchange vs Superexchange
H. Aliaga, M. T. Causa, M. Tovar +6
We present a study of the magnetic properties of the electron doped manganites Ca1-xYxMnO3 (for 0<=x<=0.25) in the paramagnetic regime. For the less doped samples (x<=0.1) the magn…
Double Exchange in Electron Doped Ca1-xYxMnO3 Manganites
H. Aliaga, M. T. Causa, A. Butera +6
We have studied structural, magnetic and transport properties as a function of temperature and magnetic field in the electron doped manganite YxCa1-xMnO3, for 0<x<0.25. We found th…
