The fluxgate ring-core demagnetization field

Journal of Magnetism and Magnetic Materials, 2006
The local demagnetization factor for the ring-core flux gate is derived analytically, based on a tangential magnetization model. The results are in good agreement with experimental data for a wide range of ring shape parameters. Approximate expressions in the limit of a narrow, thin ring are obtained, and indicate that the local demagnetization factor ...

Hybrid method for computing demagnetizing fields

IEEE Transactions on Magnetics, 1990
A hybrid finite-element-boundary integral method is proposed for computing demagnetizing field. For a three-dimensional (3-D) mesh with N nodes in the magnetic region, the method requires storage O(N/sup 4/3/), and no nodes outside the magnetic region need to be considered.

A discussion: comparison of demagnetization fields and depolarization fields

Ferroelectrics Letters Section, 2019
AbstractThe differences between demagnetization fields and depolarization fields were compared. The most fundamental reason is the existence of electric charges but the nonexistence of magnetic cha...

Analysis of a Fluxgate Incorporating Demagnetization Field

Advanced Materials Research, 2012
It is not accurate incorporating the demagnetizing field by the average demagnetizing factor due to the time variations of the permeability and the dependence of the demagnetization field on the permeability of the sample material. Especially when the magnetic field changes with the position greatly, the local demagnetizing tensor can't be simplified ...

The demagnetizing field of elliptical cylindrical domains

Journal of Physics D: Applied Physics, 1976
The average value of the perpendicular component of the demagnetizing field in case of elliptical cylindrical domains is evaluated. The value of the field is a function of the size and eccentricity of the in-plane domain geometry. The field assumes different values for different locations. The extreme values of the field at the extreme locations of the

Demagnetizing and Stray Fields of Elliptical Films

Journal of Applied Physics, 1966
The magnetostatic fields inside and outside of a ferromagnetic thin film, called demagnetizing and stray fields, respectively, are known to be calculable from the model of a uniformly magnetized flat ellipsoid. In this paper, these fields are plotted as functions of the spatial coordinates with the aspect ratios b/a and c/a as parameters.

Demagnetizing field effects on the Hahn echo

Chemical Physics Letters, 2000
Abstract Strong effects of modulated demagnetizing fields on the attenuation of Hahn echoes in liquids are shown theoretically as well as experimentally. As such demagnetizing fields are the basis of non-linear evolution leading to multiple echoes, it follows that the dominating nature of such echo signals is of a purely single-quantum character.

Thermomagnetic curves: influence of the demagnetization field

Journal of Magnetism and Magnetic Materials, 1991
Abstract We examine the influence of the demagnetization field upon the thermomagnetic curves for a disordered system of single-domain uniaxial noninteracting particles in various external fields.

Demagnetizing field in micromagnetic simulation under periodic boundary condition

Digests of the 2010 14th Biennial IEEE Conference on Electromagnetic Field Computation, 2010
The demagnetizing field in a micromagnetic simulation is studied under periodic boundary conditions. To evaluate the influence of the periodic structure, macroscopic demagnetizing factors are defined. A large demagnetizing field yields a linear magnetization where the susceptibility is given by the inverse of the macroscopic demagnetizing factor.

Demagnetizing Fields in Thin Magnetic Films

Bell System Technical Journal, 1967
Demagnetizing fields play an important role in the operation of many thin magnetic film devices. A requirement of high packing density leads to strong localization of induced changes in magnetization; and, therefore, to correspondingly large demagnetizing fields and drive currents.
