  In this Letter we analyze the coexisting ordered phases that arise in the
half-filled $\varepsilon$-t-U-V extended Hubbard Model on the square lattice
when tackled within the Kotliar andRuckenstein slave boson representation in
the thermodynamical limit. Particular emphasis is put on the dependence of the
quasiparticle dispersions, the gaps, the spin-resolved renormalization factors,
and the distribution of double occupancy on the microscopical parameters of the
model. Our calculations are performed in a parameter range that is most
suitable for resistive switching. In particular, the main contributions to the
gaps are shown to either arise from $\varepsilon$ in the weak coupling regime,
or from U and V when they are the largest scales. The gaps are thus from joint
spin and charge origin, and so are the order parameters.
