Self‐Assembly Enabled Mie‐Scattering in Hematite Nanoplatelet Stacks

Nanophotonics, Volume 15, Issue 16, 26 August 2026.
The spectral evolution during the electrolyte‐induced self‐assembly of 120 × 20 nm hematite nanoplatelets into vertical stacks in aqueous solutions is investigated. Optical simulations and correlative electron microscopy/single particle spectroscopy confirm that a collective magnetic dipole mode develops in the assembling stacks.

Developing a Functional Polyelectrolyte Hybrid Layer Scaffold Coating and Evaluation of Its Performance for Interaction With Neural Cells

Advanced Materials Interfaces, Volume 13, Issue 15, 4 August 2026.
Polyelectrolyte scaffold coatings modified with Cu and Fe3O4 nanoparticles regulate neural stem cell behavior in vitro. Increased Fe3O4 content enhances mitochondrial activity and neuronal differentiation, whereas higher Cu levels reduce cell viability.

Capacitive Scheme to Detect the Topological Magnetoelectric Effect

Physical Review Letters
The topological magnetoelectric effect (TME) is a defining property of three-dimensional $\mathbb{Z}_{2}$ topological insulators that was predicted on theoretical grounds more than a decade ago, but has still not been directly measured. In this Letter we propose a strategy for direct measurement of the TME and discuss the precision of the effect in ...

Visualizing Magnetostructural Order in Rare‐Metastable Polymorph ε‐Fe2O3 Through Domain‐Resolved Raman Spectroscopy

Small Structures, Volume 7, Issue 8, August 2026.
Raman mapping of CVD‐grown ε‐Fe2O3 flakes reveals a sixfold magnetostructural domain pattern arising from rotational twinning. A symmetry‐sensitive phonon mode encodes magnetic order, enabling noninvasive imaging of ferrimagnetic domains across cryogenic to near‐Curie temperatures.

Temperature evolution of the high‐harmonic magnetic modulations in DyFeO3

Journal of Applied Crystallography, Volume 59, Issue 4, Page 1332-1337, August 2026.
The temperature evolution of the high‐harmonic incommensurate magnetic ordering of Dy3+ in DyFeO3 orthoferrite is compared with the literature results on the soliton lattice of TbFeO3 observed in an external magnetic field.We report on the temperature evolution of magnetic satellites associated with the incommensurate magnetic ordering of Dy3+ ions in ...

Tetragonal distortion of the multiferroic compound α‐LiFe5O8 from first‐principles calculations

Journal of Applied Crystallography, Volume 59, Issue 4, Page 1307-1318, August 2026.
First‐principles calculations suggest the tetragonal space group P43212 for the multiferroic compound α‐LiFe5O8, with a direct band gap smaller than that in its widely known cubic space group P4332. The tetragonal lattice distortion a > c is explained by relatively strong antiferromagnetic exchange interactions parallel to the c axis and by Fe–O–Fe ...
