Microscopic Mechanism of Ferroelectric Properties in Barium Hexaferrites

SSRN Electronic Journal, 2022
The microscopic mechanism of the occurrence of ferroelectric properties in M-type barium hexaferrites is investigated by experimental and first-principle computation methods. The analysis of magnetic, X-ray, and Mössbauer measurements of BaFe12O19 samples ascertains the correlation between the thermal factor in the process of annealing samples and ...

Hydrogel‐Based Vat Photopolymerization of Ceramics and Metals with Low Shrinkages via Repeated Infusion Precipitation

Advanced Materials, Volume 38, Issue 8, 6 February 2026.
This work introduces an in situ precipitation strategy for the hydrogel‐based vat photopolymerization of architected ceramics and metals with reduced shrinkages and improved densities. Repeated infusion‐precipitation significantly increases metal loading within the hydrogels, which improves part quality after thermal conversion.

Element Specific Room Temperature Non‐Collinear Magnetism in the M‐Type Hexaferrite SrCo1.2Ti1.2Fe9.6O19${\rm SrCo}_{1.2}{\rm Ti}_{1.2}{\rm Fe}_{9.6}{\rm O}_{19}$

Advanced Physics Research, Volume 5, Issue 2, February 2026.
Non‐collinear magnetism is of high interest in the field of magnetoelectrics supplying a convenient mechanism to break inversion symmetry and thereby allowing for a spontaneous electrical polarization. Such “multiferroics of spin origin” are inherently suitable for electric field control of magnetism, offering a route toward low power ICT applications.

Development of Ba-hexaferrite coatings for electromagnetic wave absorption applications

, 2010
In this research, Ba-hexaferrite coatings for electromagnetic wave absorption applications were deposited bythermal spraying. A suitable powder feedstock was manufactured by blending a BaCO3+Fe2O3 mixture,which was then agglomerated by spray-drying.

Exploring Routes to Calculating the Effective Magnetic Permeability of Polymer Magnetic Composites

Polymer Composites, Volume 47, Issue 2, Page 981-988, 20 January 2026.
Schematic of a static (undeformed) configuration of the magnetic‐filled polymer network for a semi‐crystalline sample. ABSTRACT Our understanding of the effective magnetic permeability of composite materials composed of randomly dispersed metallic ferromagnetic particles within a nonmagnetic (polymer) matrix must respond to several challenges.
