• triangular holes in future magnonic and spintronic devices. Keywords: ferromagnetic antidot lattice; magnonic crystal; micromagnetic simulations; spin-wave modes; time-resolved magneto-optical Kerr effect; Introduction Recent advances in nanofabrication techniques have resulted in artificially patterned

• full range of 0° to 90°) for this type of complex magnonic crystal have not been studied earlier. Also the sharp corners of the triangular holes of the high density antidot lattice and the complicated lattice structure create inhomogeneous internal magnetic fields due to the effective pinning centres

• extensively studied the variation in the internal magnetic field profiles and demagnetizing regions for different angular orientation of the applied bias magnetic field and lattice constant for deeper understanding of the origin of the observed SW modes in such complex magnonic crystal, which was not done

• dispersion is shaped by the introduction of gap states and such a magnonic crystal can correspondingly act as a band pass filter for spin waves [19]. The present contribution covers practical aspects on the production and characterisation of antidots while the second part elucidates the various switching
