Magnetic hysteresis loops of the CoFeB thin films under different bending strains with magnetic field applied along the initial hard axis (solid dots) and easy axis (open circles). The bending strain was applied along the initial easy axis ( φ = 0°) from compressive to tensile (top to bottom shift by 120 mdeg) with ε = −7.1 × 10⁻³, −5.1 × 10⁻³, 0, 5.1 × 10⁻³, and 7.1 × 10⁻³, respectively.
