Theory of Ferrimagnetism in the Hubbard Model on Bipartite Lattices with Spectrum Symmetry

Abstract

In this paper we developed theory of the ferrimagnetism in the Hubbard model on bipartite lattices with spectrum symmetry. We then study the defect-induced ferrimagnetic orders in three models and explored the universal features.
