Epitaxial growth and magnetic properties of the first five members of the layered Sr n + 1 Ru n O 3 n + 1 oxide series
Epitaxial thin films of the n = 1 - 5 members of the layered Sr n + 1 Ru n O 3 n + 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...
