Impact of magnetic anisotropy on the magnon Hanle effect in $\alpha$-Fe${}_2$O${}_3$

Monika Scheufele, Janine Gückelhorn, Matthias Opel +5

In easy-plane antiferromagnets, the nature of the elementary excitations of the spin system is captured by the precession of the magnon pseudospin around its equilibrium pseudofiel…
