Micromagnetic Simulations in Magnonics

Chapter
Part of the Topics in Applied Physics book series (TAP, volume 125)

Abstract

We review the use of numerical micromagnetic simulations (“micromagnetics”) for investigations in magnonics, the study of spin waves and their quanta – magnons. We argue that, when used with suitable post-processing tools, micromagnetics provide the power and flexibility necessary both for interpretation of complex magnonic phenomena observed in realistic magnetic structures and devices and for prediction of novel effects. We foresee that the development of multiscale and multiphysics extensions of micromagnetic solvers will broaden both the scope of micromagnetic simulations in magnonics and the field of magnonics itself. For example, the extension of micromagnetics to solvers based on atomistic spin models will underpin application of the developed methodology to studies of phenomena involving both magnons and other fundamental excitations of the solid state. In a more distant perspective, it is highly intriguing to study spin waves in non-stationary conditions (i.e. in structures with time dependent material properties), such as those realized in experiments with samples under ultrafast optical pumping.
