Spin wave dispersion in a magnetic nanopillar with Ubermag

Published:

Step-by-step micromagnetic simulation of spin wave propagation along a Permalloy nanopillar using Ubermag (OOMMF). We reproduce the nmag probe example: relax the equilibrium state, excite spin waves with a short field pulse, and extract the dispersion relation ω(k) via 2D FFT.
