Abstract
Magnetic domains in a two-dimensional ferromagnetic metal and the existence of gapless magnons confined along the domain walls are studied starting from the XXZ model for localized spins. The relevance for transport properties of the inelastic interaction between conduction electrons and the localized magnons is analysed, and conductivity calculations presented.
