Temperature Dependence of Magnetization Damping in Heusler Alloy Films

, 2010
The Gilbert damping for $Co_2CrAl (Co_2Cr_{0.3}Fe_{0.7}Al)$ and $Ni_2MnSn$ Heusler alloy films was investigated as a function of temperature. The best films reveals the Gilbert damping nearly independent of temperature.

Residual‐Lithium‐to‐LiF Conversion Enables a LiF–Fluorinated Carbon Interphase for Reconstruction‐Resistant Ni‐Rich Cathodes

Advanced Functional Materials, EarlyView.
A fluorine‐rich acrylate monomer (PFHEA) was solvent‐free applied to NCM90 and thermally decomposed under Ar to convert residual lithium into LiF and form a pre‐built LiF/fluorinated amorphous carbon (LiF/FC) interphase. The LiF/FC layer suppresses NiO rock‐salt reconstruction and microcrack propagation, lowers interfacial resistance, and improves Li ...
