“…8, where the Co-rich samples displayed both higher peak GSI and GMI ratios than equivalent Fe-and Ni-rich ribbons. Furthermore, previous studies [40][41][42] have shown a correlation between the size of a material's GSI response and the strength of its anisotropy field, with lower anisotropy fields resulting in higher GSI ratios. This suggests that, in the absence of induced stress, the Co-rich sample possessed a lower anisotropic field than Fe-and Ni-rich samples.…”

The giant magnetoimpedance (GMI) and giant stress impedance (GSI) behaviors of amorphous ribbons composed of three commercially available materials (Co66Si15B14Fe4Ni1, Fe81B13Si3.5C2, and Ni40Fe40Si + B19Mo1−2) with differing saturation magnetostriction constants [Formula: see text] and Young's moduli ( E) were studied under longitudinal stress/strain. The linearity of the ribbons' GSI responses and gauge factors was measured to create a figure of merit and compare their stress/strain sensing performance for strains up to ɛ = 10 × 10−3. We observed that the Ni40Fe40Si + B19Mo1−2 ribbon displayed the best performance for low strains ( ɛ < 1 × 10−3), whereas the Co66Si15B14Fe4Ni1 ribbon displayed the best performance for higher strains ( ɛ < 10 × 10−3). We conclude that the suitability of a material for sensing strains in any given strain regime has a complex dependence on both [Formula: see text] and E, the former of which dictates both the absolute magnitude of the impedance variation materials exhibit (i.e., the dynamic range), while both [Formula: see text] and E control how their impedances vary with applied strain.

“…Magnetoelastic Energy (ME) is essential in the guidance of magneto-acoustic coupling motivation [ 1 , 2 , 3 , 4 ], sensor production [ 5 , 6 , 7 , 8 ], and magnetoelastic excitation [ 9 , 10 , 11 ]. Classical Magnetoelastic Energy (ME) is a linear stress function that needs to be improved when predicting some specific aspects.…”

In this letter, we propose a nonlinear Magnetoelastic Energy (ME) with a material parameter related to electron interactions. An attenuating term is contained in the formula of the proposed nonlinear ME, which can predict the variation in the anisotropic magneto-crystalline constants induced by external stress more accurately than the classical linear ME. The domain wall velocity under stress and magnetic field can be predicted accurately based on the nonlinear ME. The proposed nonlinear ME model is concise and easy to use. It is important in sensor analysis and production, magneto-acoustic coupling motivation, magnetoelastic excitation, etc.

“…This approach allows us both to find the optimum configuration of the MI element and to simulate its operation in various conditions. A lot of work has been done on modeling the MI response in thin film structures [12,24,39] including those adapted for biodetection [40]. However, there are almost no studies on modeling the MI response of amorphous ribbons particularly for specialized configurations [41,42].…”

Soft magnetic materials are widely requested in electronic and biomedical applications. Co-based amorphous ribbons are materials which combine high value of the magnetoimpedance effect (MI), high sensitivity with respect to the applied magnetic field, good corrosion stability in aggressive environments, and reasonably low price. Functional properties of ribbon-based sensitive elements can be modified by deposition of additional magnetic and non-ferromagnetic layers with required conductivity. Such layers can play different roles. In the case of magnetic biosensors for magnetic label detection, they can provide the best conditions for self-assembling processes in biological experiments. In this work, magnetic properties and MI effect were studied for the cases of rapidly quenched Co67Fe3Cr3Si15B12 amorphous ribbons and magnetic Fe20Ni80/Co67Fe3Cr3Si15B12/Fe20Ni80 composites obtained by deposition of Fe20Ni80 1 μm thick films onto both sides of the ribbons by magnetron sputtering technique. Their comparative analysis was used for finite element computer simulations of MI responses with different types of magnetic and conductive coatings. The obtained results can be useful for the design of MI sensor development, including MI biosensors for magnetic label detection.
