Abstract

• Based on the extended Hubbard model we calculate the energy of stripe and spiral ground states. We find that uniform spirals are favored by a large t'/t ratio but are unstable at small doping, tending toward stripes and checkerboard textures with spin canting. The structure of these inhomogeneities also depends on t'/t and the associated spin currents may induce a small lattice distortion associated with local dipole moments. We discuss a different kind of stripe, which appears as a domain wall of the antiferromagnetic (AF) order parameter with a fractional change of the phase of the AF order. For large vertical bar t'/t vertical bar, spirals can be stabilized under certain conditions in the overdoped regime, which may explain the elastic incommensurate magnetic response recently observed in iron-codoped Bi2201 materials.
