  The spectrum of a single hole is calculated within the spin-hole model using
a variational method. This calculation is done for any rotational invariant
magnetic background. We have found that when the magnetic background changes
from a disordered to a locally ordered state, the spectrum changes
qualitatively. We have also found that the spin pattern around the hole is
polarized. This problem is related to the study of copper oxide planes $CuO_2$
doped with a small number of holes.
