Robust Electrocaloric Performance Enabled by Highly‐Polar Frustrated Nanodomains in NaNbO3‐Based Ferrodistortive Relaxor

Advanced Functional Materials, EarlyView.
P4bm framework in NaNbO3‐Ba(Ti, Hf)O3 ferrodistortive relaxor entails short‐range and highly‐polar ferrodistortive orders. The abundant highly‐polar orders facilitate to increase entropy change, and robust octahedral oxygen tilt enables to impede thermal perturbations.

Spin Dynamics in the van der Waals Ferromagnet CrTe2 Engineered by Niobium Doping

Advanced Functional Materials, EarlyView.
Spin‐dynamic magnetic properties of van der Waals (vdW) ferromagnet 1T‐CrTe2 are tuned via niobium (Nb) as Cr1‐xNbxTe2 (x = 0–0.2). Nb doping enables wide‐band tuning of the resonance frequency from 40 GHz down to the few‐GHz regime, accompanied by a moderate increase in the Gilbert damping from ∼0.066 to ∼0.14.

Solution‐Processed Mn‐Doped 2d Perovskite Wavelength Shifters for Noble‐Liquid Photon Detection

Advanced Functional Materials, EarlyView.
Solution‐processed Mn2+‐doped PEA2PbBr4 two‐dimensional perovskite films are demonstrated as large‐area wavelength shifters for noble‐liquid photon detectors. Mn2+ incorporation introduces a broad emission band at ∼620 nm with a large Stokes shift, suppressing self‐absorption and matching SiPM sensitivity.

Domain Engineering and Anisotropic Domain‐Wall Photovoltaic Effects in Ferroelectric SnS

Advanced Functional Materials, EarlyView.
The bulk photovoltaic effect at domain walls in the in‐plane ferroelectric 2D semiconductor SnS is investigated using periodic domain structures. Unlike conventional oxide ferroelectrics, domain walls of SnS do not contribute to photocurrent generation perpendicular to the domain walls.

Atomistic Mechanisms Triggered by Joule Heating Effects in Metallic Cu‐Bi Nanowires for Spintronics

Advanced Materials, EarlyView.
Bi doped metallic Cu nanowires are promising for spintronics thanks to the stabilization of a giant spin Hall effect. However, heat resulting from current injection forces Bi to leave solution, forcing segregation into monoatomic decorations which evolve into coherent crystalline aggregates.

Generating Unconventional Spin‐Orbit Torques With Patterned Phase Gradients in Tungsten Thin Films

Advanced Materials, EarlyView.
ABSTRACT A key aim in spintronics is to achieve current‐induced magnetization switching via spin‐orbit torques without external magnetic fields. For this, the focus of recent work has been on introducing controlled lateral gradients across ferromagnet/heavy‐metal devices, giving variations in thickness, composition, or interface quality.

Anomalous Crystallinity and Magnetism in Chemically Disordered Coherent Heterostructures

Advanced Materials, EarlyView.
Coherent isostructural high‐entropy oxide heterostructures are realized despite remarkable >5% interfacial lattice distortion. The resulting buried interface exhibits abrupt valence reconstruction which contributes to 2 × enhanced exchange bias in the heterostructure relative to constituent layers, demonstrating how chemical disorder enabled anomalous ...
