title = "Effects of antidot shape on the spin wave spectra of two-dimensional Ni80Fe20 antidot lattices",
abstract = "We show that the optically induced spin wave spectra of nanoscale Ni 80Fe20 (permalloy) antidot lattices can be tuned by changing the antidot shape. The spin wave spectra also show an anisotropy with the variation of the in-plane bias field orientation. Analyses show this is due to various quantized and extended modes, whose nature changes with the antidot shape and bias field orientation as a result of the variation of the internal magnetic field profile. The observed variation and anisotropy in the spin waves with the internal and external parameters are important for their applications in magnonic devices.",
