Interfaces in 
multilayers have been examined. Two pairs of
samples each with definite x and y were prepared using the same deposition
process and the same elemental variations with the 
probe layers interfoliated
between completed V and Fe (natural abundance) layers. The only difference
was the deposition ordering. The superlattice structures were analyzed by
X-ray diffraction and Conversion Electron Mössbauer Spectroscopy at
room temperature and at 10 K. The magnetic hyperfine field distribution for the pairs
is found to be significantly different, irrespectively of the values of x, and y and can
be interpreted as due to the Fe layer being smoother than the V one. The
magnetic moments derived for the interface layer as well as for the subsequent
atomic layer are significantly lower than the calculated values.
