Query: Spin structure relation to phase contrast imaging of isolated magnetic
  Bloch and Neel skyrmions   Magnetic skyrmions are promising candidates for future storage devices with a
large data density. A great variety of materials have been found that host
skyrmions up to the room-temperature regime. Lorentz microscopy, usually
performed in a transmission electron microscope (TEM), is one of the most
important tools for characterizing skyrmion samples in real space. Using
numerical calculations, this work relates the phase contrast in a TEM to the
actual magnetization profile of an isolated Neel or Bloch skyrmion, the two
most common skyrmion types. Within the framework of the used skyrmion model,
the results are independent of skyrmion size and wall width and scale with
sample thickness for purely magnetic specimens. Simple rules are provided to
extract the actual skyrmion configuration of pure Bloch or Neel skyrmions
without the need of simulations. Furthermore, first differential phase contrast
(DPC) measurements on Neel skyrmions that meet experimental expectations are
presented and showcase the described principles. The work is relevant for
material sciences where it enables the engineering of skyrmion profiles via
convenient characterization.
