arXiv preprint: Non-local magnon transport in the compensated ferrimagnet GdIG

With friends and collaborators at the Walther Meissner Institute (WMI), TU Munich we have written a paper about non-local magnon transport in Gadolinium Iron Garnet. The experimental measurements show quite a complicated behaviour where the non-local signal changing in response to both the external magnetic field strength and the temperature. We show that  different exchange magnon modes of the bulk change frequency in response to the field and temperature depending on their polarization in qualitative agreement with the measurements.
