Lattice-Spin Mechanism in Colossal Magnetoresistant Manganites
J. A. Verges, V. Martin-Mayor, L. Brey
We present a single-orbital double-exchange model, coupled with cooperative phonons (the so called breathing-modes of the oxygen octahedra in manganites). The model is studied with…

Magnetic Domain Walls in Double Exchange Materials
Luis Brey
We study magnetic domain walls in double exchange materials. The domain wall width is proportional to the square root of the stiffness. In the double exchange model the stiffness h…
