Title: Electric Field-Controlled Magnetization in GaAs/AlGaAs Heterostructures–Chiral Organic Molecules Hybrids

Abstract

Here, we study GaAs/AlGaAs devices hostinga two-dimensional electron gas and coated with a monolayer of chiral organic molecules.We observe clear signatures of room temperature magnetism, which is induced in these systems by applying a gate voltage. We explain this phenomenon as a consequence of the spin-polarized charges that are injectedinto the semiconductor through the chiral molecules. The orientation of the magnetic moment can be manipulated by low gate voltages, with a switching ratein the MHz range. Therefore, our devices implement an efficient, electric field controlled magnetization, which has long been desired for their technical prospects.
