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

TL;DR: In this paper, spatially resolved measurements of the adiabatic temperature change are performed on a plate of gadolinium using thermography, which is used to extract the corresponding change in the local magnetic field strength.

Dependence of magnetic properties on micro- to nanostructure of CoNiFe films
Fernando M.F. Rhen,Saibal Roy +1 more
TL;DR: In this article, the magnetic properties of electrodeposited CoNiFe films with thickness varying from 0.20 to 10μm were studied and a simple model combining a morphology dependent additional contribution term to the random anisotropy model as Hc=Hcmorph+Hcanis was fitted.

TL;DR: In this article, a comprehensive characterization of the noncentrosymmetric superconductor BeAu was carried out, and it was established that the Be electrons undergo a structural phase transition from a low-temperature non-centroidymmetric FeSi structure type to a high-time temperature centro symmetric structure in the CsCl type at ${T}_{\text{s}}=860$ K.
