Fragility of the A-type AF and CE Phases of Manganites: An Exotic Insulator-to-Metal Transition Induced by Quenched Disorder
G. Alvarez, H. Aliaga, C. Sen +1
Using Monte Carlo simulations and the two eg-orbital model for manganites, the stability of the CE and A-type antiferromagnetic insulating states is analyzed when quenched disorder…
Time-dependent local Green's operator and its applications to manganites
H. Aliaga
An algorithm is presented to calculate the electronic local time-dependent Green's operator for manganites-related hamiltonians. This algorithm is proved to scale with the number o…
Theoretical Study of Half-Doped Models for Manganites: Fragility of the CE Phase with Disorder, Two Types of Colossal Magnetoresistances, and Charge-Ordered States for Electron-Doped Materials
H. Aliaga, D. Magnoux, A. Moreo +3
A comprehensive analysis of half-doped manganites is presented using Monte Carlo simulations applied to the double-exchange model with cooperative Jahn-Teller lattice distortions i…
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…
Island phases and charge order in two-dimensional manganites
H. Aliaga, B. Normand, K. Hallberg +2
The ferromagnetic Kondo lattice model with an antiferromagnetic interaction between localized spins is a minimal description of the competing kinetic t and magnetic K energy terms…
