Investigation of scaling properties of hysteresis in Finemet thin films [PDF]

, 2004
We study the behavior of hysteresis loops in Finemet Fe$_{73.5}$Cu$_1$Nb$_3$Si$_{18.5}$B$_4$ thin films by using a fluxometric setup based on a couple of well compensated pickup coils.

Fostering Innovation: Streamlining Magnetocaloric Materials Research by Digitalization

Advanced Engineering Materials, EarlyView.
Magnetocaloric cooling (MCE) is an environmentally friendly refrigeration method with great potential. Optimizing MCE materials involves the preparation and screening of large quantities of samples, which in turn generates a large amount of data. A digitalization approach is presented that uses ontologies, knowledge graphs, and digital workflows to ...

Rate-Dependent Hysteresis Model Based on LS-SVM for Magnetic Shape Memory Alloy Actuator

Actuators
Magnetic shape memory alloy-based actuators (MSMA-BAs) have extensive applications in the field of micro-nano positioning technology. However, complex hysteresis seriously affects its performance.

Dynamical hysteresis phenomena in complex network traffic [PDF]

Physical Review E, 2009
In this Brief Report, the dynamical hysteresis is investigated in constant-density traffic system of scale-free, small-world, and lattice networks. With the local-searching strategy, hysteresis persists for scale-free networks, while it disappears for small-world networks and lattice grids when the handling ability of nodes is higher than a certain ...

Simple models for dynamic hysteresis loops calculation: Application to hyperthermia optimization [PDF]

, 2010
To optimize the heating properties of magnetic nanoparticles (MNPs) in magnetic hyperthermia applications, it is necessary to calculate the area of their hysteresis loops in an alternating magnetic field.

Stochastic Dynamics in Quenched-in Disorder and Hysteresis

, 1998
The conditions under which relaxation dynamics in the presence of quenched-in disorder lead to rate-independent hysteresis are discussed. The calculation of average hysteresis branches is reduced to the solution of the level-crossing problem for the ...

Shape Memory Alloy Nanostructures With Coupled Dynamic Thermo-Mechanical Effects [PDF]

, 2014
Employing the Ginzburg-Landau phase-field theory, a new coupled dynamic thermo-mechanical 3D model has been proposed for modeling the cubic-to-tetragonal martensitic transformations in shape memory alloy (SMA) nanostructures.
