Abstract
Mean-field study of the stripe structures is
conducted for a hole-doped Hubbard model. For bond-directed stripes,
the Fermi surface consists of segments of an open surface and the
boundaries of the hole pockets which appear in the diagonal region
of momenta under certain conditions. Segments of the first type are
due to one-dimensional bands of states localized on the domain
walls. The relation of bands to the doping and temperature
dependences of the Hall constant is discussed. In connection with
the observation of quantum magnetic oscillations, a systematic
search for the electron pockets has been carried out. It is shown
that the formation of such pockets in bilayer models is quite
possible.
