Description
We study the interplay between antiferromagnetism and the paramagnetic metal-insulator-transition (PMIT) on a Bethe lattice with nearest and next-nearest neighbor hopping. For t2/t1→1 the PMIT outgrows the antiferromagnetic phase and shows a scenario similar to V2O3. We also look at other ordered phases for the doped system, where we find a ferromagnetic phase.
