Description

Occurrence of high-spin ground states in strongly-correlated electron systems is explored. In the single-band Hubbard model, high-spin states arise even for small U due to a ''k-space Hund's coupling'', which cross over to strong-U states including Nagaoka's state around the half filling. The magnetic phase diagram for the two-band Hubbard model with interband interactions is also revealed. (orig.)
