Gold Clusters With Open‐Shell Ligands: Superatom Mediated Magnetic Interaction

Angewandte Chemie, EarlyView.
Open‐shell verdazyl radicals were covalently integrated with atomically precise Ir‐doped Au12 (Ir@Au12) superatoms. The resulting radical–superatom hybrids exhibit photoinduced electron transfer, spin delocalization onto the metal‐cluster core, and weak ferromagnetic communication between radicals mediated by the superatomic electronic structure ...

Enhanced Spin‐Reorientation Transition and Polarization in DyFeO3 Thin Films

Advanced Electronic Materials, EarlyView.
Epitaxial strain in antiferromagnetic orthoferrite thin films enhances known bulk properties into a parameter range that makes them more accessible for potential applications. We show that bulk polar properties move from 4 K towards room temperature and the magnetic field‐induced AFM to FM spin‐flip in the paramagnetic Dy lattice when applying small ...

Engineering Ferrimagnetic Interactions in Molecular Quantum Systems

Angewandte Chemie, EarlyView.
Heterospin nanographene architectures—constructed by covalently linking spin‐1/2$\nicefrac {1}{2}$ and spin‐1 triangular units via on‐surface synthesis—are characterized by bond‐resolved scanning probe microscopy. Inelastic electron tunneling spectroscopy probes exchange interactions within a Heisenberg model, revealing both compensated (S=0$S=0$) and ...

Amorphous Tungsten Driving Extraordinary Long‐Range Interlayer Exchange Coupling and Large Spin‐Orbit Torque

Advanced Electronic Materials, EarlyView.
The amorphous tungsten (W) is found to be a promising non‐magnetic interlayer simultaneously driving the long‐range interlayer exchange coupling and the large spin Hall effect in a synthetic antiferromagnet (SyAF). Thanks to these characteristics, efficient spin‐orbit torque switching is achieved in the SyAF.

Mn‐Substituted Topological Phase Transition in Topological Insulator Pt2HgSe3

Advanced Electronic Materials, EarlyView.
ABSTRACT Topological materials have gained a significant interest in recent years due to their unique features, leading to topological insulators (TI), Dirac or Weyl semimetals, etc. The layered material Pt2HgSe3${\rm Pt}_2{\rm HgSe}_3$ is found to be a dual TI characterized by significant spin–orbit coupling and band inversion.

S = 3/2 Iron(I)‐Bisphosphine‐Ate Complexes: Synthesis, Characterization, and Reactivity for Electrophile Activation

Angewandte Chemie, EarlyView.
In this work, we present a new class of unusual charged Fe(I)‐bisphosphine‐ates, along with full characterization of their structure and bonding, utilizing low‐temperature synthetic and spectroscopic and techniques. These complexes are highly reactive toward catalytically relevant electrophiles, and can serve as valuable synthons providing access to ...

Exploiting Ferroelectric and Spintronic Dynamics for Neural Network Computation

Advanced Intelligent Systems, EarlyView.
Ferroelectric and spintronic devices, relying on the control of polarization and magnetization, offer intrinsically fast, durable, energy‐efficient, and low‐latency building blocks for analog in‐memory computing. The hysteretic dynamics of an order parameter are leveraged to provide nonvolatile, multistate memory and nonlinear switching. Brain‐inspired

Metal–Metal Cooperative C─F and S─F Bond Cleavage by Low‐Valent Tetracobalt Clusters and Water‐Assisted Fluoroarene Hydrodefluorination

Angewandte Chemie, EarlyView.
Self‐assembled tetrahedral CoI4 clusters supported by simple bipyridine‐based ligands undergo core rearrangement to cleave S─F and C(sp2)─F bond, forming fluoride‐bridged tetracobalt(II)‐oxo clusters, while exposure of cobalt(I) clusters to molecular oxygen yields cubane‐type cobalt(III) oxo clusters.
