Query: Skyrmion meets magnetic tunnel junction: an efficient way for electrical
  skyrmion detection investigated by ab initio theory   In our proof-of-principle study we examine the influence of skyrmions on
magnetoresistive transport. In particular, we show that magnetic tunnel
junctions are a technologically appealing and promising way for electrical
detection of non-collinear magnetic structures. The calculated effect is shown
to originate from scattering between different k-states and cannot be
identified through densities of states alone. Our results suggest that the
detection efficiency strongly depends on the utilized materials.
