“…Magnetic domains are affected by a stressinduced magn etic anisotropy. Stripe domains under stress have been observed in a variety of thin films, such as La 0.7 Sr 0.3 MnO 3 (LSMO) [9], FeCoSiB [10], permalloy (Py) [11], Ni [12], even FeC alloys [13] and FeGa bulk systems [14]. However, it is dif ficult to adjust the stress produced by the stiff crystal or glass substrate and the magnetostrictive coefficients of Py, Ni, FeC alloys, FeCoSiB, and LSMO are relatively small.…”

In this paper, we propose an approach that combines in situ mechanical-stress measurement and magnetic force microscopy (MFM) imaging and enable manipulation of the spin configuration of flexible films by tailoring the stress-induced anisotropy. We demonstrate that the stress-induced anisotropy can effectively rotate stripe domains. We see that, without the application of the magnetic field, the stripe domains tend to align parallel (perpendicular) to the direction of tensile (compressive) stress. The expansion (shrinkage) of flux-closure cap domains in response to applied tensile (compressive) stress, changes the out-of-plane stray field and the profile in the MFM image. The experimental results have been reproduced very well by micromagnetic simulations assuming a stress-induced anisotropy. Furthermore, we studied the evolution of stripe domains in the film with compressive stress against a decreasing magnetic field. It is indicated that in-plane mechanical stress can effectively convert stripe domains with Bloch walls to those with Néel walls. The observed stress-modulation of magnetic stripe domains may find application in microwave absorbers and flexible electronics.

“…The domain width decreased from 130 to 90 nm as the film thickness decreased from 120 to 80 nm; typically, thinner magnetic films give rise to reduced transition length (l 0 ) with smaller out-of-plane magnetic anisotropy. 39,40 To confirm that the formation of ordered magnetic domains is purely attributed by magnetoelastic coupling, we characterized nanotrenched Ni films on Si without PMMA sublayers (Figure S6). The resulting orientation and density of the domains were nearly identical regardless of the pattern periodicity (p).…”

“…Furthermore, we controlled the width of strip domains near the nanotrenches by changing the thickness of Ni films (Figure S5). The domain width decreased from 130 to 90 nm as the film thickness decreased from 120 to 80 nm; typically, thinner magnetic films give rise to reduced transition length ( l 0 ) with smaller out-of-plane magnetic anisotropy. , …”

The formation of ordered magnetic domains in thin films is important for the magnetic microdevices in spin-electronics, magneto-optics, and magnetic microelectromechanical systems. Although inducing anisotropic stress in magnetostrictive materials can achieve the domain assembly, controlling magnetic anisotropy over microscale areas is challenging. In this work, we realized the microscopic patterning of magnetic domains by engineering stress distribution. Deposition of ferromagnetic thin films on nanotrenched polymeric layers induced tensile stress at the interfaces, giving rise to the directional magnetoelastic coupling to form ordered domains spontaneously. By changing the periodicity and shape of nanotrenches, we spatially tuned the geometric configuration of domains by design. Theoretical analysis and micromagnetic characterization confirmed that the local stress distribution by the topographic confinement dominates the forming mechanism of the directed magnetization.

“…A simple way to submit a magnetostrictive layer to controlled mechanical stress by means of bending or stretching, is to deposit it on a flexible substrate. The effect of stress-induced anisotropy on magnetic stripe domains has been observed in various materials like (LSMO) 31 , 32 , FeCoSiB 33 , etc. Stress tunability in these materials is relatively low due to rigid substrates.…”

Flexible materials have brought up a new era of application-based research in stretchable electronics and wearable devices in the last decade. Tuning of magnetic properties by changing the curvature of devices has significant impact in the new generation of sensor-based technologies. In this work, magnetostrictive FeGa thin films have been deposited on a flexible Kapton sheet to exploit the magneto-elastic coupling effect and modify the magnetic properties of the sample. The FeGa alloy has high magnetostriction constant and high tensile strength making its properties susceptible to external stress. Tensile or compressive strain generated by the convex or concave states influence the uniaxial magnetic anisotropy of the system. Low temperature measurements show a hard magnetic behavior and the presence of exchange-bias effect after field cooling to 2 K. The results obtained in this study prove essential for the development of flexible electronics.
