Focused ion beam milled magnetic cantilevers

  • The procedure for milling micrometre scale cantilevers of lutetium iron garnet using a focused ion beam microscope was developed. The infrastructure to study these cantilevers using rotational hysteresis loops and ferromagnetic resonance experiments was set up. The cantilevers were shown to remain magnetic after milling, and the origin of their hysteresis loops investigated with a variant of the Stoner-Wohlfarth model. Ferromagnetic resonance in the cantilevers was demonstrated as the first step towards studying magnetomechanical coupling.
