摘要
We discuss the theory of extrinsic contributions to the linewidth of ultrathin ferromagnetic films, magnetized parallel to their surfaces. We invoke defect-induced two magnon scatterings, rendered active by unique aspects of dipolar contributions to spin wave dispersion in two dimensions. A two magnon shift in resonance frequency is present as well. We summarize our principal earlier conclusions, and present new results on the in-plane anisotropy of linewidth, for samples with stepped surfaces. (C) 2000 American Institute of Physics.
