Lateral shift of light reflected from a magneto-electric film
Résumé
The lateral shift of infrared light reflected from a magnetic film deposited on a non-magnetic dielectric substrate is investigated theoretically, taking into account the linear magneto-electric (ME) interaction in the magnetic film. It is shown that ME coupling leads to a six-fold increase of the shift upon reflection of a p-(s-) polarized incident wave to a s-(p-) polarized wave. Magnetization reversal leads to a nonreciprocal sign change of the shift.
