Single- and Multimagnon Dynamics in Antiferromagnetic $\alpha$-Fe${}_2$O${}_3$ Thin Films

Jiemin Li, Yanhong Gu, Yoshihiro Takahashi +8

Understanding the spin dynamics in antiferromagnetic (AFM) thin films is fundamental for designing novel devices based on AFM magnon transport. Here, we study the magnon dynamics i…
