## Abstract The influence of the surface roughness on the low energy spin wave properties is treated within a quantized phenomenological spin wave theory. Up to second order in the roughness amplitude, the surface roughness can be replaced for thin films by a nonβlocal scattering Hamiltonian acting
## Abstract A review of experimental studies of magnon excitations in manganites is presented. A microwave resonance technique, in particular a spinβwave resonance (SWR) technique, is shown to allow the study of not only bulk properties but also surface properties of manganite films. There are two
