Magnetization behavior of hard/soft-magnetic composite pillar

Journal of Magnetism and Magnetic Materials, 2008
Abstract Hard/soft-magnetic composite pillar array medium is proposed for ultra-high-density recording media. Magnetization reversal process for a single hard/soft-magnetic composite pillar in the medium is calculated using the Landau–Lifshitz–Gilbert equation.

The influences of matrix materials on the magnetic and mechanical properties of Fe78Si9B13 soft magnetic composites fabricated by injection molding

Materials research bulletin, 2021
Soft magnetic composites are fabricated via metal injection molding (MIM) of amorphous Fe78Si9B13 powder in which three kinds of binders (PA + SA, HDPE + SA, PA+HDPE + SA) are chosen as matrix materials. Because of the interaction between amino in PA and

Permeability of hybrid soft magnetic composites

Acta Materialia, 2011
Abstract The magnetic permeability of a three-phase hybrid soft magnetic composite (SMC) is formulated, extending Eshelby’s equivalent inclusion method to account for the three-phase microstructure of this SMC. The composite contains two kinds of ellipsoidal fillers dispersed in a matrix. All of the components have distinct magnetic properties.

Mimicking soft magnetic composite geometries algorithmically

International Journal of Applied Electromagnetics and Mechanics, 2019
In this paper we describe an algorithmic method to imitate geometries of soft magnetic composites. We use microscope images to determine some of the most important geometric characteristics of the material and optimize the algorithm such that the measured and simulated characteristics are in agreement.
