Barium hexaferrite ceramic permanent magnets

Suid-Afrikaanse Tydskrif vir Natuurwetenskap en Tegnologie, 1983
Barium hexaferrite ceramic permanent magnets were manufactured using a locally produced iron oxide. The effect of sintering temperature on the coercivity, remanence, shape of the hysteresis loops, density and shrinkage was studied. The results indicated that grain growth during the sintering process limited the sintering temperature to 1 200 °C for ...

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.

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.
