Abstract

We propose here to combine magnetic semiconductors and plasmonic crystals to obtain a new class of devices, in which magneto-optical effects are dramatically enhanced. So far we have studied the two building blocks separately, and we demonstrate here features of these systems that make them appealing for combination. Namely, for magnetic semiconductors we demonstrate efficient tools for manipulating their magnetization. In particular, we show that in paramagnetic (Ga,Mn)As the magnetic ions can be oriented optically. For ferromagnetic (Ga,Mn)As an ultrafast strain pulse moves the magnetization out of its equilibrium position, inducing a subsequent precessional motion about the equilibrium orientation. For plasmonic crystals, on the other hand, we show that the magneto-optical effects are dramatically enhanced in both reflection and transmission. From combining the two systems, we expect to be able to obtain magneto-optical materials that can be controlled efficiently through manipulation of the magnetization of the magnetic semiconductor onto which the plasmonic crystal is deposited.
