“…So far, inverse effect of magnetostriction was meant as a change in the magnetic state of magnetostrictive media subjected to external stresses, being strong when the magnetoelastic and magnetic anisotropy energies are comparable [2][3][4][5][6][7] . Recently, similar effect of residual stresses in a magnetostrictive film on a compliant substrate was observed 8 . In the ME laminates subjected to an external magnetic field, internal stresses emerge as a result of mechanical compliance of the phases.…”

We introduce the notion of inverse effect of magnetostriction for magnetostrictive/piezoelectric heterostructures and study this effect theoretically and experimentally. It is shown that the inverse effect of magnetostriction may crucially contribute to the mechanism of magnetoelectric coupling. It is shown that the studied effect essentially modifies the saturation magnetostriction of the whole structure as compared to its magnetic phase bulk and also induces an additional magnetic anisotropy. Our consideration provides useful insight into the fundamental issue of strain-mediated magnetoelectric coupling. Understanding this effect may lead to its utilization in original experimental concepts and the improvement of the ME coupling.Comment: 9 pages, 2 figures, accepted for publication in Applied Physics Letter

“…(11). On the contrary, an initial susceptibility-adjusted Langevin curve 7,8 for M vs H predicts unrealistically fast exponential saturation. For a Ni/PZT laminate, we have shown that, as compared to a bulk ferromagnetic, the magnetostriction of the laminate decreases, see Eq.…”

“…The use of inverse magnetostriction is a good approach for SHM, and low-cost materials with large magnetostriction are necessary [4]. Tb x Dy 1− x Fe y (0.27 ≤ x ≤ 0.30, 1.9 ≤ y ≤ 2.0), known as Terfenol-D, has giant magnetostriction and low magneto-crystalline anisotropy [5]. Calkins et al have reviewed that Terfenol-D can be widely utilized as a sensor [6].…”

Carbon fiber reinforced plastic (CFRP) is an excellent choice in the areas where weight reduction is important and multi-functionalization of CFRP, especially by adding sensor capabilities, is a promising approach to realize lightweight battery-free devices in structural health monitoring (SHM). In this study, we fabricated hybrid CFRP with Fe-Co fibers and evaluated the inverse magnetostrictive response characteristics. It was shown that the measured magnetic flux density of the CFRP fluctuates in response to cyclic bending load. It was also revealed that our Fe-Co fiber inserted CFRP has damage self-sensing ability. In addition, it seems that the optimization of design and more experimental and numerical investigation improves the capability of the hybrid CFRP with Fe-Co fiber as sensor composite materials.
