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…

Low-temperature spin dynamics in LAFO thin films: from cubic anisotropy to TLS-limited coherence
Srishti Pal, Guanxiong Qu, Hervé M. Carruzzo +6
We investigate the low-temperature spin dynamics of epitaxial lithium aluminum ferrite (LAFO) thin films using broadband ferromagnetic resonance (FMR) spectroscopy from 0.44 K to 6…
