Effect of different stages of tensile deformation on magnetic barkhausen emission in high strength low alloy steel
TL;DR: In this paper, the effect of tensile deformation on micromagnetic parameters has been studied by many researchers, and most of these studies have been done only in the elastic region and the obtained relation between magnetic parameters and the applied stress has been used to determine the residual stresses, considering that the residual stress level will not exceed the yield stress of the material.

Magnetoacoustic diagnostics of thin-walled ferromagnets with plane cracks
TL;DR: In this paper, a non-destructive method for the magnetic diagnostics of thin-walled structures based on the analysis of acoustic-emission signals was proposed, and the distribution of the magnetic field induced in a ferromagnetic half space by a magnetic dipole located over the surface of this half space was determined.

Physics of magnetism
TL;DR: Paleomagnetism is the study of the magnetic properties of rocks as discussed by the authors, and it is one of the most broadly applicable disciplines in geophysics, having uses in diverse fields such as geomagnetic, tectonics, paleoceanography, volcanology, paleontology, and sedimentology.
