By combining the real-space dynamical mean-field theory with the numerical renormalization group method, we discuss magnetic properties in the system. It is clarified how the ferromagnetically ordered ground state, which is stabilized by a flat band mechanism, is adiabatically connected to the ferrimagnetically ordered state expected in the strong coupling limit.Goescholarhttps://goedoc.uni-goettingen.de/licensesconference_paper10.1007/s10909-009-0042-5000272904600012https://resolver.sub.uni-goettingen.de/purl?gs-1/6804
