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…
Current induced magneto-optical Kerr effect as a probe of Dirac carriers in BiSb alloy
Ryota Miyazaki, Shunzhen Wang, Guanxiong Qu +4
We study the current-induced magneto-optical Kerr effect (MOKE) in BiSb semi-metalic alloys. The MOKE signal is found to be the largest in pure Bi (), exceeding th…
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…
