Extended Data Fig. 4: Estimation of VCMA Coefficient.
(a, c) Minor R(H) loops acquired on a WCell ≈ 300 nm SK-MTJ, with varying DC bias voltages, VDC of +1 V, 0 V, and −1 V (top to bottom) applied to the TE of the MTJ. (b, d) Variation with VDC of (b) perpendicular energy, E⊥ (represented by shaded regions in a). Red line indicates a linear fit, with extrapolated x-intercept ∼ +3.95 V.
