Query: Realization of Ordered Magnetic Skyrmions in Thin Films at Ambient
  Conditions   Magnetic skyrmions present interesting physics due to their topological
nature and hold significant promise for future information technologies. A key
barrier to realizing skyrmion devices has been stabilizing these spin
structures under ambient conditions. In this manuscript, we exploit the tunable
magnetic properties of amorphous Fe/Gd mulitlayers to realize skyrmion lattices
which are stable over a large temperature and magnetic field parameter space,
including room temperature and zero magnetic field. These hybrid skyrmions have
both Bloch-type and N\'eel-type character and are stabilized by dipolar
interactions rather than Dzyaloshinskii-Moriya interactions, which are
typically considered required for the generation of skyrmions. Small angle
neutron scattering (SANS) was used in combination with soft X-ray microscopy to
provide a unique, multi-scale probe of the local and long-range order of these
structures. These results identify a pathway to engineer controllable skyrmion
phases in thin film geometries which are stable at ambient conditions.
