Using an exact diagonalization method within the dynamical mean-field theory we found stable stripe phases in the two-dimensional Hubbard model doped by 0.03<\ensuremathδ<0.2 holes, with a crossover from diagonal to vertical site-centered stripes at doping \ensuremathδ\ensuremath≃0.05. The doping dependence of the size of magnetic domains and chemical potential shift \ensuremathΔ\ensuremathμ\ensuremath∝\ensuremath-\ensuremathδ2 are in quantitative agreement with the experimental results for La_2\ensuremath-xSrxCuO4. The one-dimensional metallic behavior along the domain walls explains the observed suppression of spectral weight along the Brillouin zone diagonal.
