The system consists of magnetic dipoles exhibiting the Faraday effect.

A scattering approach is used to analyze the momentum transfer.

Abstract

We consider a scattering formulation of radiative momentum transfer to a Magneto-Chiral system that is subjected to a constant background magnetic field. The system takes the form of a collection magnetic dipoles that exhibit the Faraday effect. It is shown that the first non-trivial contribution of the momentum transfer to the object from the radiation field occurs at fourth order in the Born series.
