Summary: The analysis and optimization of devices with soft magnetic cores rely on a precise modelling of their nonlinear anhysteretic magnetization, which can be achieved through the physically-based Langevin-Weiss equation. Retrieving the modelling parameters given an experimental anhysteretic curve can be challenging, but a simple and deterministic method has been presented in this work. The key finding is that the Langevin-Weiss function can accurately describe the anhysteretic magnetization of any homogeneous material, even those with strong transverse uniaxial anisotropy, if the Weiss molecular field is allowed to be negative.

Summary: The physical behavior of a magnetic material can be characterized by the Jiles-Atherton (J-A) model, but errors exist in model parameter identification, especially in calculating iron loss. This paper proposes a new error criterion, a modified J-A model, and tests their effectiveness in improving agreement between calculated and experimental results.

Summary: The magnetic field generated by ferromagnetic materials of underwater detectors is affected by seawater pressure, impacting the accuracy of deep-sea resource exploration. A magnetomechanical numerical model must be developed to simulate the influence of deep-sea pressure on the magnetic field. This article presents a magnetomechanical coupling model of an oxygen tank developed in COMSOL Multiphysics. The experimental results show the relationship between magnetization irreversibility, pressure, and the spatial magnetic field.

Summary: Electrical steels are commonly used in large-scale transformers and electric motors. However, accurately describing their anhysteretic magnetization is challenging. In this study, researchers proposed a law of partial magnetizations for magnetic mixtures and introduced a graphical method and fitting approach for analyzing and modeling anhysteretic magnetization curves. The results demonstrated the effectiveness of the proposed method in accurately describing the magnetization curves of different materials.

Summary: Developing a transient magneto-mechanical numerical model is crucial to accurately simulate the influence of deep-sea pressure on the magnetic field around underwater detectors. This study improved the Jiles-Atherton theory for complex stress and verified the hysteresis effect between magnetization and stress by calculating the variation in magnetic field with pressure. The effect of stress on magnetic field was determined by calculating the magnetic field distribution under different pressures.

Summary: The Jiles-Atherton model is crucial for studying hysteresis loops, and the parameter identification of this model has attracted great attention from scholars worldwide. In this paper, a new algorithm based on the Levy whale optimization algorithm (LWOA) is proposed to overcome the local optimum issue in the existing whale optimization algorithm (WOA). The new algorithm, named C-LWOA, demonstrates improved stability and calculation accuracy in parameter identification, as shown by experiments and simulations. The algorithm is also highly competitive with other metaheuristic optimizers in benchmark functions and engineering problems.

Summary: The aim of this paper is to harmonize the Jiles-Atherton (J-A) static hysteresis loop models presented by different authors at different publication dates. The reviewed papers, which explain the hysteresis loop model of magnetic materials originally developed by Jiles, are taken into consideration due to their different variable nomenclature and even physical meaning. The inconsistency between Jiles' referenced works is shown, and the consequences are presented as differences in BH curve behaviors and calculated static hysteresis losses on the application level. The harmonization of J-A hysteresis models is presented and confirmed by numerical calculations and measured data.

Summary: Virgin and Yb-implanted epitaxial ZnO films grown using ALD were investigated by XAS. The polarization dependence of the films determined by the orientation of the polarization vector of the synchrotron radiation to the sample surface was revealed. The implantation and subsequent annealing were found to have an important influence on the native point defect complexes in the ZnO. The presence of donor-acceptor complexes in the samples was confirmed through the comparison of experimental and modelled spectra.

Summary: Carbon steel is crucial in the global economy and its carbon content's precise knowledge plays a vital role in determining its mechanical and magnetic properties. Magnetic Barkhausen noise, magnetic hysteresis loop, and impedance measurements are reliable tools for assessing carbon content. A multifunctional induction coil sensor is designed and optimized for measuring MBN, MHL, and impedance signals. The study theoretically analyzes and experimentally verifies the parabolic dependence of MBN envelope's maximum value on carbon content, and explains the relation between coercive field, remanence, impedance, and carbon content through analytical simulations.

Summary: Assessing the direct effect of temperature on magnetic flux leakage (MFL) signal is complicated due to nonlinear coupling. However, temperature-dependent magnetic dipole models have been proposed to model this effect. The models have been validated by experiments on a non-oriented grain silicon steel specimen and show good agreement with the experimental results. They can be used as effective tools to understand the influences of temperature and thermal stress on MFL signals and accurately size defects when temperature is involved.

Summary: This work investigates the electronic structure modification of scandia-ceria stabilized zirconia (10Sc1CeSZ) ceramics sintered at different temperatures. Through XRD, SEM, impedance spectroscopy, and XPS analysis, it was found that the increase in sintering temperature led to higher grain ionic conductivity, accompanied by reduced porosity, increased grain size, and a shift from rhombohedral to cubic phase. XPS also revealed a surface modification in the ceramic, with the lower sintering temperature showing more Zr-OH bonds.

Summary: We experimentally studied the dynamics of single and double ball chains in a highly viscous silicon oil under gravity. Single ball chains were found to often rotate and not remain planar, while shorter chains formed distorted U shapes and longer chains formed distorted W shapes. Our experiments with single ball chains were successfully reproduced in numerical simulations of a single elastic filament. In addition, two ball chains in our experiments were observed to move away or approach each other depending on their initial distance.
