Magnomechanics in suspended magnetic beams

Cavity optomechanical systems have become a popular playground for studies of controllable nonlinear interactions between light and motion. Owing to the large speed light, realizing cavity optomechanics in microwave frequency range requires cavities up several mm size, hence making it hard embed them on same chip. An alternative scheme with much smaller footprint is provided by magnomechanics, where electromagnetic replaced magnet undergoing ferromagnetic resonance, coupling originates from magnetic shape anisotropy. Here, we consider magnomechanical interaction occurring suspended beam, which both mechanical modes physically overlap can also be driven individually. We show that sizable produced if beam has some initial static deformation, as often case due unequal strains constituent materials. how magnetism affects magnetomotive detection vibrations, magnomechanics used signal amplification. Finally, discuss experimental progress towards scheme.
