Alexey A. Kovalev, Gerrit E.W. Bauer, and Arne Brataas
TL;DR
This paper predicts magnetovibrational modes in a nano-magnetomechanical system, which could be used for advanced sensors and actuators, and suggests these modes can be detected via ferromagnetic resonance spectra.
Contribution
It introduces the concept of magnetovibrational coupling in small cantilevers and predicts polaritonic modes for the first time.
Findings
Magnetovibrational modes are predicted in nano-magnetomechanical systems.
Polaritonic modes can be observed through ferromagnetic resonance line splittings.
Potential applications include sensors and actuators.
Abstract
A nano-magnetomechanical system consisting of a cantilever and a thin magnetic film is predicted to display magnetovibrational modes, which should enable applications for sensors and actuators. The {}``polaritonic{}'' modes can be detected by line splittings in ferromagnetic resonance spectra.
