TLDR
Granular inclusions, grain boundaries, lamellar precipitates, and the crystalline surface have been examined as possible nucleation centers for domains of reverse magnetization in ferromagnetic materials as discussed by the authors.Abstract:
Granular inclusions, grain boundaries, lamellar precipitates, and the crystalline surface have been examined as possible nucleation centers for domains of reverse magnetization in ferromagnetic materials. It is concluded that the surface density of magnetic poles at the grain boundaries ${\ensuremath{\omega}}^{*}$ is the most common source of nucleation energy in polycrystalline materials.read more

Jahn-teller phenomena in solids
TL;DR: In this paper, the Jahn-Teller phenomena encountered in oxides are reviewed briefly and the influence of dynamic deformations at a crossover from localized to itinerant electronic behavior in a mixed-valent system is discussed.

Ferromagnetic Domain Theory
TL;DR: In this article, the authors present a broad review of the physical principles of domain theory and of the crucial experiments which bear directly on the foundations of the subject of ferromagnetic domains.

Summary of losses in magnetic materials
TL;DR: In this article, the phenomenological Landau-Lifshitz equation is used to quantitatively express the various manifestations of the residual losses in magnetic materials, and possible physical mechanisms contributing to the phenomenologically introduced Landau Lifting damping term are qualitatively discussed.

Magnetic Materials for Digital‐Computer Components. I. A Theory of Flux Reversal in Polycrystalline Ferromagnetics
N. Menyuk,John B. Goodenough +1 more
TL;DR: In this paper, the authors proposed a theoretical model for the magnetization reversal in polycrystalline ferro- and ferrimagnetic materials, which is mainly due to the nucleation and growth of 180° Bloch walls.

Single-Domain Wall Propagation and Damping Mechanism during Magnetic Switching of Bistable Amorphous Microwires
TL;DR: From quantitative analysis of the propagating wall characteristics, a new damping is theoretically introduced as arising from structural relaxation which dominates in the low temperature regime.
