A commonly used model of magnetic multilayers, namely the linear chain of
classical spins is reconsidered in the zero anisotropy limit. Numerical
minimisation of the Heisenberg energy functional shows that the often
neglected effects due to the finiteness of the number of magnetically
coupled layers result in a variety of fascinating spin configurations.
Zero anisotropy minimum energy spin configurations are applied to fitting
synchrotron Mössbauer reflectometric spectra of a [Fe-57/FeSi]x10
multilayer on an amorphous substrate. Our results are in favor of loose
interlayer coupling of the Fe layer closest to the substrate. }
