Bulk‐Edge Correspondence and Multiplexing Topological Routings in Gyromagnetic Photonic Weyl Metamaterials

Laser &Photonics Reviews, Volume 20, Issue 1, 8 January 2026.
In this work, various topological phases and the bulk‐edge correspondence are studied and established in gyromagnetic photonic Weyl metamaterials. Based on rigorous theoretical analysis, the comprehensive depictions of the multiple topological phase diagrams and multi‐type bulk‐edge correspondences are further mapped out.

Large Room‐Temperature Exchange Bias in Y3Fe5O12 via Antiparallel Exchange Interaction with Magnetically Pinned CoFe2O4 Nanoparticles

Small, Volume 22, Issue 1, 2 January 2026.
In spintronics technology, magnetic insulators such as yttrium iron garnet can provide energy‐efficient data transfer capabilities based on the exchange bias effect. Composites fabricated by combining cobalt ferrite with yttrium iron garnet show promise for spintronics applications because of their improved EB at room temperature.

Nucleation of magnetisation reversal, from nanoparticles to bulk materials [PDF]

, 2006
We review models for the nucleation of magnetisation reversal, i.e. the formation of a region of reversed magnetisation in an initially magnetically saturated system.

Toward Enhancing Chiro‐Optical and Magneto‐Optical Properties of Magnetic Nanocrystals by Surface Plasmons

Advanced Optical Materials, Volume 13, Issue 34, December 2, 2025.
Here, recent progress is highlighted in colloidal magnetoplasmonic hybrid nanomaterials, with a focus on chiral plasmonics. Metal nanocrystals with intrinsic chiroptical features can lead to a combination of chiral plasmonics and magneto‐optics effects when interacting with the magnetic counterpart, offering a foundation for systematically designing ...

Polaritonic quantum matter

Nanophotonics, Volume 14, Issue 23, Page 3723-3760, 02 November 2025.
Abstract Polaritons are quantum mechanical superpositions of photon states with elementary excitations in molecules and solids. The light–matter admixture causes a characteristic frequency‐momentum dispersion shared by all polaritons irrespective of the microscopic nature of material excitations that could entail charge, spin, lattice or orbital ...

Effect of Low-Spin Fe^(2+) on the Composition of the Lower Mantle [PDF]

, 1973
The effects of low-spin Fe^(2+) in the earth's lower mantle are investigated in considerable detail. The existence of low-spin Fe^(2+) permits the formation of an extra phase, since Mg^(2+) and low-spin Fe^(2+) probably do not form solid solutions.

Transducer Materials Mediated Deep Brain Stimulation in Neurological Disorders

Advanced Functional Materials, Volume 35, Issue 46, November 12, 2025.
This review discusses advanced transducer materials for improving deep brain stimulation (DBS) in neurological disorders. These materials respond to light, ultrasound, or magnetic fields, enabling precise, less invasive neuromodulation. Their stimulus‐responsive properties enhance neural control and adaptive therapy, paving the way for next‐generation ...
