摘要：

The phase diagram of model Mott-insulator-band-insulator heterostructures is studied using the semiclassical approximation to the dynamical-mean-field method as a function of thickness, coupling constant, and charge confinement. An interface-stabilized ferromagnetic phase is found, allowing the study of its competition and possible coexistence with the antiferromagnetic order characteristic of the bulk Mott insulator.
