The dependence of the interface quality on growth temperature in (001) single-crystal multilayers was investigated using conversion electron Mössbauer spectroscopy (CEMS) and X-ray diffraction (xrd). The samples, with 7 atomic layers () of isotope-enriched and 5 of , were grown by dc magnetron sputtering onto (001) substrates at temperatures in the range 230–430. The xrd results confirmed the previous findings on optimum temperature for sharp interfaces (–330), whereas the CEMS data suggested that the short-range order was similar in all samples with . The film grown at 430 was significantly different, with clear signs of alloying throughout the layers. Additional magneto-optical measurements showed the expected ferromagnetic behaviour.
