A (Ga, Mn)As/GaAs superlattice, a semiconductor-based ferromagnetic/non-magnetic multilayer system, was prepared by low-temperature molecular beam epitaxy. X-ray diffraction measurements showed that the superlattice structure has high crystal perfection and good interface quality. Magnetotransport measurements revealed the presence of ferromagnetic order in the multilayer system at low temperatures.
