• We have succeeded in growing for the first time Mn_2As thin films on GaAs(001)using molecular beam epitaxy. Bulk Mn_2As is a layered antiferromagnetic material. Single-crystalline films with the c axis perpendicular to the substrate were grown directly on the GaAs substrates, as well as on MnGa seed layers, where MnGa is a ferromagnet. We also grew MnGa/Mn_2As/MnGa trilayers, and we found interlayer coupling with oscillatory spacer layer thickness dependence. The coupling strengths at room temperature were up to -0.63mJ/m^2 (antiferromagnetic) and +0.53mJ/m^2 (ferromagnetic). The oscillation period was between 0.95 and 1.55nm, which is close to the period of the antiferromagnetic order in Mn_2As(1.25nm). The sign of the magnetoresistance was correlated with the sign of the interlayer coupling in the same way as was found earlier for MnGa/(Mn, Ga, As)/MnGa trilayers.
