We report new types of metallic stripes with ferromagnetic order along the domain walls for the two-dimensional Hubbard model using the dynamical mean-field theory. The (1,0) stripes have the obsd. filling close to one doped hole per two atoms, while the (1,1) stripes are more extended. The stripe structures are stable at low temps. T < 70K, and change into spin spirals at higher temps.
