Large‐Scale Growth of Self‐Poled Ferroelectric Rashba Semiconductor α‐GeTe(111) Thin Films: A Crucial Step Towards Future CMOS‐Compatible Ferroelectric Spintronic Devices

Advanced Science, EarlyView.
Ferroelectric Rashba semiconductors promise ultralow‐power devices but lack industry‐quality films. This work demonstrates CMOS‐compatible fabrication of high‐quality α‐GeTe(111) films via magnetron sputtering, enabled by a 5 nm Sb2Te3 seed layer. Structural and ferroelectric analyses show robust, switchable polarization comparable to MBE films, paving

The magnetization behavior and magnetic viscosity of Sm(Co, Fe, Cu, Zr)Z ribbons with different temperature dependence of coercivity

, 2010
Two types of Sm(Co, Fe, Cu, Zr)(Z) ribbons with different temperature dependence of coercivity are investigated in comparison at different temperatures. It is found that their magnetization behaviors and magnetic viscosity are distinctly different.

COERCIVITY MECHANISMS IN OXIDE MAGNETS

, 1977
L'observation par microscopie électronique de spécimens de ferrite de barium ne révèle ni l'existence d'une seconde phase ni l'existence de défauts ou inclusions aux joints de grains. En considérant les parois de Bloch comme une suite discrète de moments

Outstanding TC Enhancement in 5d–3d Y2NiIrO6 by Compression

Advanced Science, EarlyView.
Double perovskite Y2NiIrO6 with half filed 3d eg–5d t2g configuration, exhibits first experimental example of pressure‐enhanced magnetic interaction in iridate and iridate‐related systems. Its Curie temperature increase from 192 to 243 K at 17 GPa. Herein, the orthogonal eg–t2g pathway remains robust even under compression‐induced lattice distortion ...

Magnetic structure and coercivity mechanism of AlNiCo magnets studied by electron holography

, 2017
Micromagnetic structure and coercivity were systematically investigated by electron holography and micromagnetic simulation. The experimental data show that the distribution of magnetic flux lines of FeCo-rich (alpha 1) phase is different from that of ...

A Multimodal Magnetically Driven Soft Robot With Integrated Actuation‐Sensing Based on Photothermal Reprogramming Technology

Advanced Science, EarlyView.
This work reports a thermally safe, photothermally reprogrammable magnetic soft robot with its reprogramming temperature tuned to ∼39.5°C for biocompatibility. It achieves multimodal locomotion (max speed of 1.8 BL/s) and integrates liquid‐metal capacitive sensing to monitor self‐motion and detect environmental changes in simulated gastric environments,

Magnetically Boosted Water‐Splitting Performance in Metallic Glasses

Advanced Science, EarlyView.
A strategy for boosting water electrolysis efficiency using ultralow magnetic fields on soft‐magnetic MG wires is reported. Ni40Fe40P20 metallic glass exhibits superior overall water‐splitting performance (1.51 V @ 1000 mA cm−2) at 100 Oe, enabled by spin polarization in periodic surface magnetic domains to enhance orbital hybridization and net spin ...

Large Temperature‐invariant Anomalous Nernst Effect in Non‐collinear Antiferromagnet Mn3Pt

Advanced Science, EarlyView.
Based on the noncollinear antiferromagnetic Mn3Pt thin films, the composition‐tunable Mn‐3d orbital states directly govern the Berry curvature. As a result, a giant and temperature‐invariant anomalous Nernst coefficient of 0.71 µV/K is achieved under Mn‐rich conditions.
