RT Journal Article T1 Monte Carlo determination of the phase diagram of the double-exchange model A1 Alonso, J. L. A1 Capitán, J. A. A1 Fernández Pérez, Luis Antonio A1 Guinea, F. A1 Martín Mayor, Víctor AB 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.
