Imprinting Electrically Switchable Scalar Spin Chirality by Anisotropic Strain in a Kagome Antiferromagnet

Advanced Science, EarlyView.
It is shown that anisotropic strain offers a novel approach to control the magnetic ground state in heterostructures of a Kagome antiferromagnet, unlocking new functionalities. This strain induces finite scalar spin chirality, resulting in a pronounced Berry curvature in momentum space, leading to room‐temperature anomalous Hall effect.

Resonant Spin Amplification and Accumulation in MAPbI3 Single Crystals

Advanced Science, EarlyView.
Carrier spin dynamics are studied in a 20 µm thin MAPbI3 perovskite single crystal using time‐resolved Kerr ellipticity at cryogenic temperatures. Long spin relaxation (30 ns) and dephasing (21 ns) enable spin accumulation. Spin accumulation effects are discussed in detail along with carrier‐nuclear spin interactions.

Oxygen Vacancy Defect Engineering for Transverse Thermoelectric Enhancement: a Novel Extrinsic Pathway beyond Intrinsic Approaches

Advanced Science, EarlyView.
Transverse thermoelectric (TE) technology gains increasing attention as it enables efficient power generation within a single TE element and eliminates junctions. This study enhances transverse thermopower in polycrystalline Sr3YCo4O10‐δ through oxygen vacancy defect engineering, utilizing the anomalous Nernst effect to improve TE efficiency.

Superior Capacitive Energy Storage of BaTiO3‐Based Polymorphic Relaxor Ferroelectrics Engineered by Mesoscopically Chemical Homogeneity

Advanced Science, EarlyView.
BaTiO3‐based polymorphic relaxor ferroelectrics are engineered by mesoscopically chemical homogeneity, constructing diversified nanodomain architectures with similar multiple local symmetries but different nanodomain scales in diverse grains. Ex‐/In situ multiscale structure analysis indicates that a relatively continuous polarization switching with ...

Mn3SnN‐Based Antiferromagnetic Tunnel Junction with Giant Tunneling Magnetoresistance and Multi‐States: Design and Theoretical Validation

Advanced Science, EarlyView.
A non‐collinear Mn3SnN/SrTiO3/Mn3SnN (001) AFMTJ is proposed with a theoretical TMR exceeding 1500%, enabled by optimal momentum (k)‐space matching between Mn3SnN's spin‐polarized Fermi surface (pk||${p}_{{\bm{k}}_{\mathbf{|}\mathbf{|}}}$) and the low‐decay‐rate (κk||${\kappa}_{{\bm{k}}_{\mathbf{|}\mathbf{|}}}$) of the SrTiO3 barrier.
