We investigated the magnetic properties of a (110)-oriented 
multilayer
of the form 
Å 
Å 
Å 
Å 
consisting of 260 Å thick 
layers and 12 Å thick 
layers
which were grown epitaxially on a 
single crystal. The easy axis of magnetization
is the [001] direction as determined by polarized neutron reflectometry.
Neutron diffraction data reveal that the commensurate spin density wave is
the stable phase at 
and the magnetic moments are aligned perpendicular
to [001]. When rotating the magnetization from the easy axis into the
in-plane hard-axis direction ![$[1\bar 10]$](/articles/epl/abs/2000/04/5961/5961_tex_eq13.png)
by applying a magnetic field of 
the
intensity of the commensurate 
peak decreases by a factor of 2. This
can be interpreted as a simultaneous rotation of the and moments pinned
together in its initial perpendicular orientation.
