Abstract

2D materials have many fascinating features, and here we report on the potential levitation of an ultra-thin magnetic material above a planar Au plate facilitated by repulsive Casimir forces. We considered a system consisting of an electric plate facing a magnetic plate. Through an investigation of the magnetic plate parameters, we show enhancement of the repulsion in a configuration where the plate has nm-scale thickness and a large permeability near ω=0. Additionally, high system temperatures can be used to enhance the effect. Magnetic 2D materials are thus excellent candidates for large-Casimir-repulsion systems and could be configured for levitation.
