Magnetization Dynamics in Quasiperiodic Magnonic Crystals
Riya Mehta, Bivas Rana, Susmita Saha
Quasiperiodic magnonic crystals, in contrast to their periodic counterparts, lack strict periodicity which gives rise to complex and localised spin wave spectra characterized by nu…
Optical excitation and detection of high-frequency Sezawa modes in Si/SiO2 system decorated with Ni80Fe20 nanodot arrays
