Spin waves in striped phases
Spin waves in striped phases
In many antiferromagnetic, quasi-two-dimensional materials, doping with holes leads to ``stripe'' phases, in which the holes congregate along antiphase domain walls in the otherwise antiferromagnetic texture. Using a suitably parametrized two-dimensional Heisenberg model on a square lattice, we study the spin wave spectra of well-ordered spin stripes, comparing bond-centered antiphase …
