Epitaxial thin films of the n=1-5 members of the layered Sr{sub n+1}Ru{sub n}O{sub 3n+1} oxide series were produced by reactive molecular-beam epitaxy. X-ray diffraction and high-resolution transmission electron microscopy confirm that these films are epitaxially oriented and nearly phase pure (>98%). The Sr{sub 2}RuO{sub 4} (n=1) and Sr{sub 3}Ru{sub 2}O{sub 7} (n=2) samples show no ferromagnetic transition in the range from 5 to 300 K, while the Sr{sub 4}Ru{sub 3}O{sub 10} (n=3), Sr{sub 5}Ru{sub 4}O{sub 13} (n=4), and Sr{sub 6}Ru{sub 5}O{sub 16} (n=5) samples show ferromagnetic transitions at 85, 95, and 130 K, respectively.
