Conductance in the Helimagnet- and Skyrmion-Lattice-Embedded Electron Waveguide

In this paper, we investigated the conductance properties in the helimagnet (HM)- and skyrmion lattice (SL)-film-embedded electron waveguide (WG) and found that under translation of the HM/SL layer the conductance contour as a function of the layer center demonstrates nearly identical pattern to the original spin field contour. When a WG electron is scattered by the embedded impurity, the HM/SL spin texture distorts the spin-dependent wavefunction. By interference between different quantum paths the electron experiences, the HM/SL spin texture is recorded in the conductance. The scheme also provides a possible detect of the HM/SL spin configuration by transport experiment.
