Spin-Lattice Dynamics and Interactions in Magnonic Spinels
Hari Paudyal, Yuri Suzuki, Michael E. Flatté +1
Minimizing magnetic damping while understanding spin-lattice interactions remains a key challenge for magnonics. We show site-specific Al/Li ordering in spinel ferrites drives a fe…
Microscopic Understanding of Thermal-magnon Transport in Low-damping Ferrimagnetic Thin Films
Lerato Takana, Katya Mikhailova, Junwei Tong +9
Thermally generated magnons enable heat-driven spin transport in magnetic insulators, yet the relative importance of multiple microscopic mechanisms governing their propagation rem…
Understanding Damping Mechanisms via Spin Diffusion Length in Low-damping LiAlFeO Spinel Ferrite Thin Films
Katya Mikhailova, Lerato Takana, Guanxiong Qu +5
The mechanisms underlying magnon damping are of fundamental and technological interest in low-damping materials. We find low-damping ferrimagnetic insulator LiAlFe$…
Nearly Isotropic Magnon Transport in Epitaxial Lithium Aluminum Ferrite Thin Films
Yiming Li, Katya Mikhailova, Lerato Takana +9
Low-loss magnetic insulating thin films are promising for information transport via magnons, where isotropic in-plane magnon propagation is desirable. We report nonlocal measuremen…
