TLDR
In this paper, the demagnetizing factors of ellipsoids of three different axes are presented, along with supplementary formulas which cover a large number of special cases of ellipses.Abstract:
Charts and tables of the demagnetizing factors of prolate and oblate spheroids are readily available; however, demagnetizing factors of ellipsoids of three different axes are incompletely tabulated and laborious to calculate. This article presents charts and tables which make possible easy determination of the demagnetizing factor for any principal axis of an ellipsoid of any shape. Formulas for the demagnetizing factors of the general ellipsoid are included together with supplementary formulas which cover a large number of special cases.read more

Microwave absorption properties of the Ni nanofibers fabricated by electrospinning
TL;DR: In this paper, Ni nanofibers with an average diameter of about 100 nm were synthesized by a simple and cost-effective electrospinning technology and the complex permittivity and permeability properties were measured in the frequency range of 1-15 GHz.

TL;DR: In this article, the effects of spin misalignment scattering on the magnetic properties of martensitic steel samples are investigated and it is revealed that the amount of spin-misalignment scatter is very sensitive to the applied heat treatment and is most pronounced in the as-quenched condition.

Theoretical considerations on the anhysteretic remanent magnetization of interacting particles with uniaxial anisotropy
TL;DR: In this paper, an analytical approach is used to calculate the ARM susceptibility of a system of interacting single-domain (SD) particles, based on a statistical description of the interaction field.
