Atomically Modulating Competing Exchange Interactions in Centrosymmetric Skyrmion Hosts GdRu2X2 (X = Si and Ge)

Advanced Electronic Materials, EarlyView.
Our work bridges the gap between skyrmion discovery and material design by demonstrating how atomic‐scale control of exchange interactions enables tunable skyrmion phase transitions in centrosymmetric magnetic metals. ABSTRACT Magnetic skyrmions are topologically protected spin states that hold promise for shaping the future of electronics.

Atomic Scale Control of Thermal Conductivity in LaMnO3/SrMnO3 Superlattices

Advanced Electronic Materials, EarlyView.
Interface‐dominated cross‐plane thermal transport in [(LaMnO3)m/(SrMnO3)n]10 superlattices can be controlled by the octahedral rotation/tilt angle φOOR of the MnO6 octahedra, which as well is controlled by the “m/n” ratio. ABSTRACT We report atomic scale structure and phonon thermal transport in (LaMnO3)m/(SrMnO3)n/SrTiO3(100) superlattices (LMO/SMO ...

Selective Tuning of Perpendicular Magnetic Anisotropy and Dzyaloshinskii–Moriya Interaction in Heterostructures Compatible with Magnetic Tunnel Junctions

Advanced Electronic Materials, EarlyView.
ABSTRACT Chirally coupled magnetic tunnel junctions (MTJs) have been proposed as a route toward compact spin logic architectures. Micromagnetic simulations indeed show that chiral coupling between adjacent MTJs with perpendicular magnetic anisotropy (PMA) can be achieved through an in‐plane (IP) interconnection mediated by the Dzyaloshinskii–Moriya ...

Magnesium‐Retention Assisted Synthesis of High‐Performance Zintl Thermoelectrics

Angewandte Chemie, EarlyView.
Mg volatilization and chemical instability during high‐temperature synthesis hinder the scalable fabrication of Mg‐based thermoelectrics. Here, a magnesium‐retention assisted synthesis (MRAS) strategy stabilizes Mg using a sacrificial Mg reservoir and an inert‐gas‐regulated melting environment.

Selenocyanate Driven Organic Cations Homogenization in Wide‐Bandgap Perovskite

Advanced Energy Materials, EarlyView.
Selenocyanate pseudohalide doping stabilizes 1.66 eV wide‐bandgap formamidinium (FA)‐based perovskite lattices via strong FA+ hydrogen bonding and matched ionic radii. Uniform cation distribution and suppressed ion migration reduces defect losses, delivering >24% single‐junction efficiency and 32.66% perovskite/silicon tandem performance with ...
