Abstract
Two-dimensional Ising ferromagnets with spins perpendicular to the plane are destabilised by dipole interactions. Ferromagnetism is destroyed by domain walls which, at low temperatures, form a square network on a square lattice. At higher temperatures, domain walls form a floating solid, the period of which decreases continuously with increasing temperature.Keywords
