ErMn6Sn6: A Promising Kagome Antiferromagnetic Candidate for Room‐Temperature Nernst Effect‐Based Thermoelectrics

Advanced Functional Materials, EarlyView.
This work investigates the Nernst effect in the Kagome magnet ErMn6Sn6 which exhibits both topological and anomalous Nernst effects with the anomalous Nernst coefficient reaching 1.71 µV K⁻¹ at 300 K. This value surpasses that of most canted antiferromagnetic materials, making ErMn6Sn6 a promising candidate for advancing thermoelectric devices based on

Control of Ferromagnetism of Vanadium Oxide Thin Films by Oxidation States

Advanced Functional Materials, EarlyView.
The nonstoichiometric VOx exhibits a distinct ferromagnetic hysteresis loop and demonstrates a high magnetic susceptibility (χ=dMdH$ = \frac{{dM}}{{dH}}\;$∼10). Micromagnetic simulations show the results of the “partial volume fraction ferromagnetic phase model” for VOx/Co/Pt structure.

ASAD: Adaptive Seasonality Anomaly Detection Algorithm under Intricate KPI Profiles

Applied Sciences, 2022
Anomaly detection is the foundation of intelligent operation and maintenance (O&M), and detection objects are evaluated by key performance indicators (KPIs). For almost all computer O&M systems, KPIs are usually the machine-level operating data. Moreover,

Enhanced Magnetization Switching Efficiency via Orbital‐Current‐Induced Torque in Ti/Ta (Pt)/CoFeB/MgO Structures

Advanced Functional Materials, EarlyView.
The orbital‐current‐induced torque is investigated as an efficient method for controlling magnetization direction. By introducing Ti as an orbital current source in Ti/Ta (or Pt)/CoFeB/MgO structures, the switching current is reduced by ∼25% compared to a conventional spin‐orbit torque structure of Ta/CoFeB/MgO.
