The Interplay of Crystal‐Field Transitions and Exchange Spin Dynamics in a Ferrimagnet

Advanced Physics Research, EarlyView.
Temperature‐dependent THz spectroscopy reveals strong hybridization between Yb3+ CEF excitations and Yb–Fe exchange dynamics in Gd3/2Yb1/2BiFe5O12. Near the magnetization compensation temperature, spectral weight is redistributed between the coupled modes, while the Yb–Fe exchange mode exhibits an anomalous redshift upon cooling due to CEF‐mediated ...

Demagnetization Parameters Evaluation of Magnetic Shields Based on Anhysteretic Magnetization Curve

, 2023
To achieve the nearly zero-field environment, demagnetization is an indispensable step for magnetic shields composed of high-permeability material, which adjusts the magnetization of the material to establish magnetic equilibrium with the environmental ...

Infinite Functional Versatility, Formidable Limits: Evaluating Gallium‐Based Liquid Metals in Rechargeable Batteries

Carbon Energy, EarlyView.
Beyond the hype surrounding the self‐healing properties of gallium‐based liquid metals (Ga‐LMs), this perspective critically examines their functional roles in metal‐ion batteries, highlighting both their underlying merits and the often‐overlooked challenges, including non‐representative design and testing configurations, performance overestimations ...

Multiple Ultrafast Pathways of Photo‐Induced Magnetic Phase Transition in FeRh Thin Films

Small, EarlyView.
Photoexcited FeRh exhibits a transient PM‐like spin‐disordered state within ∼1 ps, preceding delayed ferromagnetic stabilization. Terahertz electrodynamics reveals this hidden intermediate state and identifies multiple non‐equilibrium pathways for the photo‐induced antiferromagnetic‐to‐ferromagnetic transition. ABSTRACT Strong interplay among electron,

Influences of the demagnetizing field on dynamic behaviors of the magnetic domain wall in ferromagnetic nanowires

Acta Physica Sinica, 2012
Understanding of magnetic domain wall dynamic behavior is one of the important issues in the realization of spintronic device based on domain wall motion. We investigate the dynamic behaviors of the magnetic domain wall propagation in L-shaped ferromagnetic nanowires under external magnetic driving fields.
