TLDR
In this paper, a mathematical model of the hysteresis mechanisms in ferromagnets is presented based on existing ideas of domain wall motion including both bending and translation, which gives rise to a frictional force opposing the movement of domain walls.About:

TL;DR: Repeated dietary shifts demonstrated that most changes to the gut microbiota are reversible, while also uncovering bacteria whose abundance depends on prior consumption, emphasizing the dominant role that diet plays in shaping interindividual variations in host-associated microbial communities.

Theory of the magnetomechanical effect
TL;DR: In this paper, the authors investigated a model theory of the changes in magnetization that a ferromagnetic material undergoes when subjected to an applied uniaxial stress and showed that the effect can be described by an equation in which the rate of change of magnetization with elastic energy is proportional to the displacement of the magnetization from the anhysteretic magnetization.

Numerical determination of hysteresis parameters for the modeling of magnetic properties using the theory of ferromagnetic hysteresis
TL;DR: In this article, various model parameters needed to describe hysteresis on the basis of the Jiles-Atherton theory can be calculated from experimental measurements of the coercivity, remanence, saturation magnetization, initial anhysteretic susceptibility, initial normal susceptibility, and maximum differential susceptibility.

Modeling and control of hysteresis in magnetostrictive actuators
Xiaobo Tan,John S. Baras +1 more
TL;DR: A novel dynamic model is proposed for the hysteresis in magnetostrictive actuators by coupling a Preisach operator to an ordinary differential equation, and a parameter identification method is described.

Size dependence of specific power absorption of Fe3O4 particles in AC magnetic field
TL;DR: In this article, the specific absorption rate (SAR) values of aqueous suspensions of magnetite particles with different diameters varying from 7.5 to 416nm were investigated by measuring the time-dependent temperature curves in an external alternating magnetic field (80 kHz, 32.5 kA/m).

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.

Some theoretical aspects of rock-magnetism
TL;DR: In this paper, a brief theoretical study of the most typical magnetic properties of rocks is devoted to the magnetic viscosity due to thermal agitation in small grains and in larger ones.
