Line Plot from Scientific Research

Low-field magnetoconductance G ( H ) measured for increasing values of accumulated electron density n e (legend), at constant D / 0 = -0.26 V nm -1 (see Supplementary Fig. 7 for analogous data at positive D / 0 ). The hysteresis caused by the finite magnetization of electrons occupying spin-polarized bands becomes less pronounced and the magnetic field at which the hysteresis ends (that is, the coercive field) becomes smaller upon increasing n e . Both quantities eventually vanish at approximately 78 10^12 cm^-2. The feature associated to the spin-flop transition (indicated by the grey dashed lines) also shifts to lower magnetic fields, becomes less pronounced and eventually disappears on the same n e scale.
