Coupled nanomechanical
resonators made of two-dimensional materials
are promising for processing information with mechanical modes. However,
the challenge for these systems is to control the coupling. Here,
we demonstrate strong coupling of motion between two suspended membranes
of the magnetic 2D material FePS
3
. We describe a tunable
electromechanical mechanism for control over both the resonance frequency
and the coupling strength using a gate voltage electrode under each
membrane. We show that the coupling can be utilized for transferring
data between drums by amplitude modulation. Finally, we also study
the temperature dependence of the coupling and how it is affected
by the antiferromagnetic phase transition characteristic of this material.
The presented electrical coupling of resonant magnetic 2D membranes
holds the promise of transferring mechanical energy over a distance
at low electrical power, thus enabling novel data readout and information
processing technologies.
