  Spin waves in magnetic nanowires can be bound by a local bending of the wire.
The eigenfrequency of a truly local magnon mode is determined by the curvature:
a general analytical expression is established for any infinitesimally weak
localized curvature of the wire. The interaction of the local mode with spin
waves, propagating through the bend, results in scattering features, which is
well confirmed by spin-lattice simulations.
