Spin and charge ordering in three-leg ladders in oxyborates
E. Vallejo, M. Avignon
We study the spin ordering within the 3-leg ladders present in the oxyborate Fe(3)O(2)BO(3) consisting of localized classical spins interacting with conduction electrons (one elect…
Spin-orbit induced chirality of Andreev states in Josephson junctions
Andres A. Reynoso, Gonzalo Usaj, C. A. Balseiro +2
We study Josephson junctions (JJs) in which the region between the two superconductors is a multichannel system with Rashba spin-orbit coupling (SOC) where a barrier or a quantum p…
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…
Anomalous Josephson Current in Junctions with Spin-Polarizing Quantum Point Contacts
A. A. Reynoso, Gonzalo Usaj, C. A. Balseiro +2
We consider a ballistic Josephson junction with a quantum point contact in a two-dimensional electron gas with Rashba spin-orbit coupling. The point contact acts as a spin filter w…
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…
Magnetic Moment Formation in Quantum Point Contacts
P. S. Cornaglia, C. A. Balseiro, M. Avignon
We study the formation of local magnetic moments in quantum point contacts. Using a Hubbard-like model to describe point contacts formed in a two dimensional system, we calculate t…
