Abstract
We study the magnetic phases of the single-band Hubbard model within the self-consistent Hartree-Fock formalism applied to a large supercell. We find that incommensurate spin-density waves gradually deform into domain walls with increasing correlation energy U, in agreement with previous studies. For U/t>8 the domain walls evaporate into separated magnetic polarons. For U/tKeywords
