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.

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.

Hard and soft magnetic composites with modified magnetic properties

World Journal of Engineering, 2011
The paper deals with methods of tailoring magnetic properties of soft and hard magnetic composites. Comparison of magnetic properties of injection moulding and compression moulding Nd-Fe-B magnets are presented. Magnetic properties of Nd-Fe-B bonded magnets were tailored by different ways such as: amount of resin, addition of barium ferrite, Al or Fe ...

Application of soft magnetic composites in active magnetic bearings

IECON 2011 - 37th Annual Conference of the IEEE Industrial Electronics Society, 2011
One of the main application areas of active magnetic bearings is turbo machinery. Such machines run at high speeds and through application of magnetic bearing bearings mechanical contact and friction between rotor and stator can be avoided. Nevertheless magnetic bearings still cause rotor losses through eddy currents and magnetic hysteresis effects ...

3D Magnetic Reluctivity Tensor of Soft Magnetic Composite Material

2006 12th Biennial IEEE Conference on Electromagnetic Field Computation, 2006
Soft magnetic composite (SMC) materials are particularly suitable for construction of electrical machines with complex structure and 3D magnetic flux. For design and analysis of such 3D flux machines, 3D magnetic properties of the magnetic materials should be properly determined, modeled and applied for calculating the magnetic field distribution ...
