Query: A streamlined approach to mapping the magnetic induction of skyrmionic
  materials   Recently, Lorentz transmission electron microscopy (LTEM) has helped
researchers advance the emerging field of magnetic skyrmions. These magnetic
quasi-particles, composed of topologically non-trivial magnetization textures,
have a large potential for application as information carriers in low-power
memory and logic devices. LTEM is one of a very few techniques for direct real
space imaging of magnetic features at the nanoscale. For Fresnel-contrast LTEM,
the transport of intensity equation (TIE) is the tool of choice for
quantitative reconstruction of the local magnetic induction through the sample
thickness. Typically this analysis requires collection of at least three
images.Here we show that for uniform thin magnetic films which includes many
skyrmionic samples, the magnetic induction can be quantitatively determined
from a single defocused image using a simplified TIE approach.
