Boosts in Polarization and Piezoelectric Responses of Lead‐Free Ferroelectrics through Strain‐Enhanced Glassy Coexistent Polars with High Dynamics

Advanced Science, EarlyView.
An effective strategy by constructing strain‐enhanced glassy coexistent polars near ferroelectric tricritical point to simultaneously improve polarization response and reduce energy loss is uncovered in (Ba0.84Ca0.16)0.985Bi0.01(Ti0.9Zr0.07Sn0.03)1‐x/100Hfx/100O3 (xHf) system and verified by phase‐field simulations with supporting high resolution ...

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.

Designing Spin Symmetry for Altermagnetism with Strong Magnetoelectric Coupling

Advanced Science, EarlyView.
Antiferromagnets can be induced into altermagnets by changing the real‐space symmetry, increasing their potential for use in spintronic devices. Here, a novel and general approach is proposed: transforming antiferromagnets into altermagnets by modulating spin‐space symmetry, rather than real‐space symmetry.

Sparse Nanocrystals Enable Ultra‐Low Coercivity and Remarkable Mechanical Robustness in High‐Entropy Amorphous Alloy

Advanced Science, EarlyView.
An order modulation strategy is introduced to overcome trade‐off between mechanical and magnetic properties by constructing an amorphous‐nanocrystalline transitional structure in a ferromagnetic HEA system. This enable the resultant alloys to combine an ultra‐low coercivity of 0.3 A m−1 with a remarkable mechanical toughness, thereby achieving a ...

Ferrocene‐Functionalized Black Phosphorus Nanoplatform Enables Targeted and Prolonged MRI Visualization of Atherosclerotic Plaques

Advanced Science, EarlyView.
Aminoferrocene is employed to modify black phosphorus, generating stable phosphorus radicals (FcP). The FcP is then functionalized with hyaluronic acid (HA) to produce the HA‐FcP radical complex, thereby developing a novel, highly efficient, sensitive, long‐lasting, and low‐heavy‐metal‐content radical contrast agent for targeted imaging of ...
