Abstract

Epitaxial thin films of the n=1-5 members of the layered Srn+1 Run O3n+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 Sr2 Ru O4 (n=1) and Sr3 Ru2 O7 (n=2) samples show no ferromagnetic transition in the range from 5 to 300 K, while the Sr4 Ru3 O10 (n=3), Sr5 Ru4 O13 (n=4), and Sr6 Ru5 O16 (n=5) samples show ferromagnetic transitions at 85, 95, and 130 K, respectively.
