Magnetic polaron structures in the one-dimensional double and super-exchange model
E. Vallejo, F. López-Urías, O. Navarro +1
An analytical and numerical study of the one-dimensional double and super-exchange model is presented. A phase separation between ferromagnetic and anti-ferromagnetic phases occurs…
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…
New Type of Charge and Magnetic order in the Ferromagnetic Kondo Lattice
D. J. Garcia, K. Hallberg, C. D. Batista +2
We study numerically the one dimensional ferromagnetic Kondo lattice, a model widely used to describe nickel and manganese perovskites. By including a nearest neighbor Coulomb inte…
Electron-Doped Manganese Perovskites: The Polaronic State
C. D. Batista, J. M. Eroles, M. Avignon +1
Using the Lanczos method in linear chains we study the ground state of the double exchange model including an antiferromagnetic super-exchange in the low concentration limit. We fi…
