Scatter Plot from Scientific Research

The carrier density evolution of the coercive field extracted from b and c, and of the uniaxial magnetic anisotropy K extracted from the analysis of the spin-flip field in parallel and perpendicular magnetic field, shows that the two quantities are proportional. The error bars for the coercive field correspond to the width of the jump shown in b. K and its error bars are extracted using the same method used to extract the data shown in Fig. 2e.
