DC‐magnetometry Analytical Tool Driven by Spin Ordering Phenomena for Sensing Chemical Interactions at the Surface of Nanomaterials

Advanced Science, EarlyView.
The adsorption of AsV on akaganeite nanorods was found to provide a magnetic signature. A change in the surface spin order gave rise to a second peak in the zero‐field cooled curve. AsIII adsorption does not provide any change in the magnetic behavior of the sorbent.

Molecular Sieve Promoted Growth of Ferroelectric Trilayer 3R‐MoS2 for Polarization‐Dependent Reconfigurable Optoelectronic Synapses

Advanced Science, EarlyView.
The noncentrosymmetric trilayer rhombohedral‐stacked MoS2 nanoflakes with enhanced sliding ferroelectric properties are synthesized via a molecular sieve‐assisted chemical vapor deposition process. The switchable polarization states, combined with the exceptional light/gate voltage modulated electrical properties of these nanoflakes, enable broadband ...

A Spin‐Texture Spin‐Valves With Van Der Waals Magnets

Advanced Science, EarlyView.
ABSTRACT All‐electrical methods for nucleating, detecting, and manipulating spin textures in 2D van der Waals (vdW) magnets can serve as fundamental building blocks for multi‐state spintronic memory, logic, and neuromorphic computing applications.

Exchange Length Tailored Magnetic Resonance for Broadband Absorption in FeCo‐Based Alloys

Advanced Science, EarlyView.
To break the high‐frequency magnetic loss bottleneck in soft magnetic alloys, a magnetic exchange length (Lex)‐guided strategy is proposed. Cu doping increases Lex and intergranular coupling, which effectively reduces magnetic anisotropy and pushes the exchange resonance to 12.0 GHz.

Morphotropic Phase Boundary in Graft Poly(Vinylidene Fluoride‐co‐Tetrafluoroethylene) With High Curie Temperature

Advanced Science, EarlyView.
The first TrFE‐free ferroelectric polymers exhibiting concurrently a morphotropic phase boundary and high Curie temperature are reported through a grafting strategy, which is completely different from previous methods to design MPB by composition and irradiation. This finding offers a cost‐effective solution to decode the long‐standing inverse relation
