Fig. 4: Characteristic magnetic property changes in a strained Ni nanostructure.
From: Direct observation of tensile-strain-induced nanoscale magnetic hardening
a, b Fresnel defocus images of the Ni nanostructure, demonstrating directional control of magnetization by stress. The double-headed arrow marks the applied strain direction. c Effect of the height of the Ni nanostructure (H) on magnetic domain size (S) at fixed tensile strain (0.20 ± 0.05%). The linear fit is S = 0.58H-0.24, with an adjusted R-squared value of 0.85. d Micromagnetic simulations of Ni nanostructures of varying height at 0.20% strain showing changes in magnetic domain density. The scale bars in (a) and (d) are 500 nm.
