Research case study: Graded index magnonics

"We find that, even when you apply a small magnetic field across a domain wall, which is uniform everywhere but oscillates in time, you can generate spin waves (see Figure 2). Importantly, we find that it isn't the motion of the domain wall which generates spin waves (as many papers presume) - it is created simply because of the presence of the domain wall's graded index, along with the uniform external field."
