Special Issue Information

Dear Colleagues,

The magnetoelastic Villari effect has been known for over one hundred years. Previously it was commonly used for the development of high measurement range force sensors, called pressductors or tensductors. Such sensors were successfully used in industrial applications, e.g., enabling robust and reliable measurements of high masses in silos and tanks, stress monitoring in cable bridges, etc.

However, recently developed magnetic materials create new possibilities in the utilization of magnetoelastic effects. As a result, magnetoelastic research has received a fresh impetus, especially due to the development of microscale applications. A wide range of magnetoelastic effects (such as Villari effect, Wiedemann effect, Barrett effect, stress-impedance as well as Guillemin effect) are applied for the development of microscale, high-end sensors for mechatronics, bio-medical assessment, chemical detection, or nanometrology applications. The development of such sensors requires a novel approach for functional materials research and characterization. Moreover, sensors application creates new challenges in advanced signal processing and transducer interfacing.

This Special Issue will present the recent state of the art in the magnetoelastic research, creating the space for experience exchange and scientific discussion for further cooperation.

A Simplified Sablik’s Approach to Model the Effect of Compaction Pressure on the Shape of Hysteresis Loops in Soft Magnetic Composite Cores
Materials 2020, 13(1), 170; https://doi.org/10.3390/ma13010170 - 01 Jan 2020

A novel approach to take into account the effect of compaction pressure on the shape of modeled hysteresis curves of self-developed soft magnetic composite cores is presented. The description relies on the introduction of an additional term in the so-called effective field, which is assumed proportional to the compaction pressure. The proposed model bears some resemblance to the Sablik’s extension of the Jiles–Atherton model, readily used in the studies of the magnetoelastic effect. Verification of the description is carried out using measurement data from self-developed iron-based composite cores. Full article

This paper presents a new method of modeling the influence of mechanical stresses on a magnetic permeability tensor of soft magnetic materials. The proposed method utilizes the principal stresses concept to compensate the influence of shear stresses. As a result, the stress dependence of a magnetic permeability tensor may be assessed with only the knowledge about the influence of axial stresses on magnetic properties of isotropic material. The proposed method was used for a finite element method based model of a tensductor designed for measurements of tensile forces. Due to the fact that 2D stresses distribution occurs in a tensductor, simplification of both principal stresses and a magnetic permeability tensor rotation procedure was proposed. As a result, good agreement was reached between the results of modeling and the results of experimental tests. This result validates the possibility of utilization of the proposed modeling method for the design of magnetomechanical devices. Full article

The domain wall (DW) dynamics of amorphous and nanocrystalline Co-based glass-coated microwires are explored under the influence of stress annealing. Different annealing profiles have enabled remarkable changes in coercivity and magnetostriction values of Co-based amorphous microwires with initially negative magnitude, allowing induced magnetic bistability in stress-annealed samples and, consequently, high DW velocity has been observed. Similarly, Co-based nanocrystalline microwires with positive magnetostriction and spontaneous bistability have featured high DW velocity. Different values of tensile stresses applied during annealing have resulted in a redistribution of magnetoelastic anisotropy showing a decreasing trend in both DW velocities and coercivity of nanocrystalline samples. Observed results are discussed in terms of the stress dependence on magnetostriction and microstructural relaxation. Full article

The significant strain dependence of the hysteretic Giant Magnetoimpedance (GMI) effect in a Co67Fe3Cr3B12Si15 amorphous alloy in a low magnetizing field is presented. A simplistic test stand capable of continuous measurements of GMI characteristics under the influence of strain is detailed. Based on the results, a stress-impedance (SI) sensor is proposed, with a gauge factor similar to semiconductor strain gauges but more robust. An effective method of minimizing external magnetic field influence on the SI effect is given. Full article
