The modified procedures in coercivity scaling*

open access: yesArchives of Electrical Engineering, 2015
The paper presents a scaling approach to the analysis of coercivity. The Widom-based procedure of coercivity scaling has been tested for non-oriented electrical steel. Due to insufficient results, the scaling procedure was improved relating to the method

On the remarkable coercivity in MnBi by microstructural engineering [PDF]

open access: yesAPL Materials
MnBi materials with different microstructures were prepared by severe plastic deformation using different processing conditions. The coercivity can be controlled by tuning the grain size, defect density, and the phase distribution of the MnBi in the ...

Coercivity of Integrals versus Coercivity of Integrands

open access: yesJournal of Mathematical Analysis and Applications, 1995
Considering the integral functional of the calculus of variations \[ I(u)=\int_{\Omega} f(x,u(x),\nabla u(x)) dx \] where \(\Omega\subset \mathbb{R}^n, u:\Omega \to \mathbb{R},\) the authors discuss the possibility that a coercivity assumption on \(I\) implies an analogous property on the integrand.

Improvement in Magnetic Properties of PLD-Made Nd-Fe-B Thick Film Magnets [PDF]

open access: yes, 2008
Coercivity of pulsed laser deposition (PLD)-fabricated Nd-Fe-B thick film magnets were enhanced by synergistic use of an additive (Zr, Nb or Ga) and an adoption of pulse annealing as a high-speed crystallization method.
