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.

Structure and magnetic properties of W-type hexaferrites

IUCrJ, 2019
W-type hexaferrites (WHFs) (SrMe2Fe16O27, Me = Mg, Co, Ni and Zn) are hard magnetic materials with high potential for permanent magnet applications owing to their large crystalline anisotropy and high cation tunability.

Room‐Temperature Multiferroic Liquids: Ferroelectric and Ferromagnetic Order in a Hybrid Nanoparticle–Liquid Crystal System

Advanced Materials, Volume 37, Issue 41, October 16, 2025.
A hybrid fluid combining ferrimagnetic nanoplatelets and a ferroelectric nematic displays coexisting magnetization and polarisation at room temperature. This self‐assembled multiferroic shows strong magnetoelectric effect and nonlinear optical response, offering a soft, reconfigurable platform for next‐generation sensing, actuation, and photonic ...

Hexaferrite multiferroics: from bulk to thick films

Journal of Physics: Conference Series, 2018
Abstract We report studies of the structural and microstructural properties of Sr3Co2Fe24O41 in bulk form and as thick films. The precursor powders for the bulk form were prepared following the sol-gel auto-combustion method. The prepared pellets were synthesized at 1200 °C to produce Sr3Co2Fe24O41.
