Optimizing the Jiles-Atherton Model of Hysteresis by a genetic algorithm
Modeling magnetic components for simulation in electric circuits requires an accurate model of the hysteresis loop of the core material used. It is important that the parameters extracted for the hysteresis model be optimized across the range of ...

Significant nanoscale oxygen diffusion coefficient variations are measured in ferroelectric hafnium zirconium oxide films with grain boundaries and electrode interfaces exhibiting values 104 times larger than the grain cores. Overall coefficients are 10X larger for films prepared with metal nitride electrodes compared to refractory metals. New insights

Iron Losses Prediction with PWM Supply Using Low and High Frequency Measurements: Analysis and Results Comparison [PDF]
In this paper, two different methods for iron loss prediction are analyzed. The first method is based on the classical separation of loss contributions (hysteresis, eddy-current, and excess losses).

Electrocapillary Modulated Interfacial Tension Amplifies Liquid Metal Transduction
This study presented an electrocapillary‐enhanced magnetohydrodynamic pumping strategy that harnesses the Lorentz force and interfacial tension modulation of liquid metal droplets to achieve amplified fluidic power. The system enabled low‐voltage, self‐oscillating fluidic transduction with enhanced pressure and flow generation, supporting compact ...

A giant magnetic coercivity and a vertical shift of hysteresis loops are demonstrated in Sr3YCo4O10+δ epitaxial films. The hard magnetic behavior originates from ferromagnetic spin bags stabilized within a long‐range ordered oxygen‐vacancy structure.

Hysteresis losses along open transformations
It is shown that the analytical theory of hysteresis, which determines the value of J at the end of an arbitrary path of H if the magnetization curve and the saturation loop are known, can be extended to compute the energy losses due to hysteresis along an arbitrary transformation, open or closed, in the (J, H) plane.
