# Scattering theory of transport through disordered magnets

@article{Jakobsen2019ScatteringTO, title={Scattering theory of transport through disordered magnets}, author={Martin Fonnum Jakobsen and Alireza Qaiumzadeh and Arne Brataas}, journal={Physical Review B}, year={2019} }

We present a scattering theory of transport through noncollinear disordered magnetic insulators. For concreteness, we study and compare the random field model (RFM) and the random anisotropy model (RAM). The RFM and RAM are used to model random spin disorder systems and amorphous materials, respectively. We utilize the Landauer-Buttiker formalism to compute the transmission probability and spin conductance of one-dimensional disordered spin chains. The RFM and the RAM both exhibit Anderson…

It is demonstrated that topologically protected magnon edge states are robust to moderate disorder and, as anticipated, localized in the strong regime, and it is shown that bulk-boundary correspondence holds for disordered topological magnons.
