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…
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…
Spin-polarons in an exchange model
O. Navarro, E. Vallejo, M. Avignon
Spin-polarons are obtained using an Ising-like exchange model consisting of double and super-exchange interactions in low dimensional systems. At zero temperature, a new phase sepa…
Structural distortion in Ludwigites
E. Vallejo, G. Calderon
Structural distortion in a three-leg-ladder is studied in connection with Ludwigites, in particular the Fe and Co homometallic ones. Static impurities in t_{2g}-orbitals as infinit…
