Abstract
We present a two-dimensional 4-sublattice square lattice system, and investigate 4-band effects in magnetism by using spin susceptibility. The spin susceptibility of the sublattice system is calculated. The present results suggest that many-band systems doped with hole have some interesting magnetic properties. We present a two-dimensional 4-sublattice square lattice system, and investigate 4-band effects in magnetism by using spin susceptibility. The spin susceptibility of the sublattice system is calculated. The expression of the effective exchange integral in Heisenberg model is derived within the random-phase approximation by using Hubbard model and the spin susceptibility. The present results suggest that many-band systems doped with hole have some interesting magnetic properties.
