Temperature Evolution of Magnon Propagation Length in Tm${}_3$Fe${}_5$O${}_{12}$ Thin Films: Roles of Magnetic Anisotropy and Gilbert Damping

Amit Chanda, Christian Holzmann, Noah Schulz +7

The magnon propagation length ($⟨\xi ⟩$) of a ferro/ferrimagnet (FM) is one of the key factors that controls the generation and propagation of thermally-driven spin curren…
