【 摘 要 】

The fermionic Ising spin glass is analyzed for arbitrary filling and for all temperatures. A self-organized three-band structure of the model is obtained in the magnetically ordered phase. Deviation from half-filling generates a central nonmagnetic band, which becomes sharply separated at T=0 by (pseudo)gaps From upper and lower magnetic bands. Replica symmetry breaking effects are derived fur several observables and correlations. They determine the shape of the three-band density of states, and, for given chemical potential, influence the fermion filling strongly in the low-temperature regime.
