A joint publication of the Kläui - Lab together with Olena Gomonay and Jairo Sinova about magnon transport in weak antiferromagnets has been published in the Journal of Magnetism and Magnetic Materials.
In more detail, they studied the antiferromagnet hematite with the Dzyaloshinskii-Moriya interaction (DMI). The results show that the DMI gives a new reconfigurability in the long distance magnon transport within thin films. This introduces a hysteresis in the system as a consequense of a competiotion of the Zeeman field and the effective field of the DMI.
