Abstract
Quasiperiodic magnonic crystals, in contrast to their periodic counterparts,
lack strict periodicity which gives rise to complex and localised spin wave spectra
characterized by numerous band gaps and fractal features. Despite their intrinsic
structural complexity, quasiperiodic nature of these magnonic crystals enables better
tunability of spin wave spectra over their periodic counterparts and therefore holds
promise for the applications in reprogrammable magnonic devices. In this article, we
provide an overview of magnetization reversal and precessional magnetization dynamics
studied so far in various quasiperiodic magnonic crystals, illustrating how their
quasiperiodic nature gives rise to tailored band structure, enabling unparalleled control
over spin waves. The review is concluded by highlighting the possible potential
applications of these quasiperiodic magnonic crystals, exploring potential avenues for
future exploration followed by a brief summary.
