Abstract
We study the phase diagram of the double exchange model, with antiferromagnetic interactions, in a cubic lattice both at zero and finite temperature. There is a rich variety of magnetic phases, combined with regions where phase separation takes place. We identify phases, intrinsic to the cubic lattice, which are stable for realistic values of the interactions and dopings. Some of these phases break chiral symmetry, leading to unusual features.
Description
© 2001 The American Physical Society. We want to warmly thank Víctor Laliena for a pleasant and fruitful collaboration. It is also a pleasure to thank B. Alascio, A. Aligia, E. Dagotto, and B. Normand, for discussions on this problem. We acknowledge financial support from Grant Nos. PB96-0875, AEN97-1680, AEN97-1693, AEN99-0990 (MEC, Spain), and (07N/0045/98)(C. Madrid). V.M.-M. was supported by the Ministerio de Educación y Cultura. The simulations were carried out in RTNN computers at Zaragoza and Madrid.
