Description
The topological stability of skyrmions in bulk samples of MnSi and the
observation of spin transfer torque effects at ultra-low current densities
have generated great interest in skyrmions in chiral magnets as a new
route towards next generation spintronics devices. Yet, the formation
of skyrmions in MBE grown thin films of MnSi reported in the literature
is highly controversial. We report gracing incidence small angle
neutron scattering (GISANS) of the magnetic order in selected thin
films of MnSi grown by state of the art MBE techniques. In combination
with polarised neutron reflectometry (PNR) and magnetisation
measurements of the same samples our data provide direct reciprocal
space information of the incommensurate magnetic order, clarifying
the nature of magnetic phase diagram.
