Periodic arrays of magnetic stripe defects are fabricated by Cr+ ion implantation on a 30 nm permalloy lm. Modifying the mean ion penetration depth, the defect height can be controlled, which allows an investigation of the gradual transition from a magnetic thin lm towards a magnonic crystal.
Spin wave dispersion and two-magnon scattering are studied using brillouin light scattering (BLS) as well as broadband ferromagnetic resonance (FMR). The obtained results are corroborated by theoretical calculations based on a perturbation theory.
