A Polar Topology Network Induces Elastic Stiffening in Ferroelectric Oxide Superlattices

Small, EarlyView.
The periodicity in BiFeO3/SrTiO3 superlattices tunes the system into a dense, elastically constrained polar texture state. This topology‐rich regime reveals a collective mechanical response in which interactions among polar topological defects restrict local deformations, producing a pronounced elastic stiffening.

Crucial Role of Magnetic Dipole and Anomalous Field Dependence in NiPS3

Small, EarlyView.
Torque magnetometry on the prototypical 2D anisotropic magnet NiPS3, together with relativistic density functional theory calculations, uncovers a distinct intrinsic magnetic anisotropy. The characteristic torque pattern, driven by a high‐field spin‐flop transition, reveals its magnetic response beyond standard XY or XXZ models and highlights the ...

A Comprehensive Multimodal Study of La0.45Sr0.45TiO3 Structure as Matrix for the Exsolution Process: From the Average to the Local Scale

Small, EarlyView.
We present a multimodal, multiscale study of La0.45Sr0.45TiO3 combining experimental and computational approaches to probe its local structure. The results reveal A‐site ordering along [001] and loss of centrosymmetry driven by electrostatic effects.

Magnetic Structure of the High‐TN Antiferromagnet La0.5Sr3.5Fe3O7.5F2.6: A Temperature‐Dependent Mößbauer Spectroscopy and Neutron Diffraction Study

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
La0.5Sr3.5Fe3O7.5F2.6, a rare n = 3 Ruddlesden–Popper oxyfluoride, exhibits robust antiferromagnetism across a wide temperature range from 1.7 to 470 K. Temperature‐dependent neutron diffraction reveals an orthorhombic nuclear and a monoclinic magnetic structure, while Mößbauer spectroscopy shows persistent short‐range magnetic order up to 525 K.
