a Color-scale maps of TMF signal \({R}_{{nl}}\left(B,n\right)\) measured in sample 1 at 1.5 K (top right: electron side; bottom left: hole side). The broken lines show the theoretically calculated focusing peaks at \({\lambda }_{{SOC}}=13.9\) meV. Inset: carrier trajectories for the first and second focusing peaks (top left and bottom right, respectively). b TMF map and c the corresponding 1D cuts measured in sample 2 at 1.5 K at n (in 1012 cm-2) = −0.62, −0.78, −0.93, −1.09, −1.24, −1.40, and −1.56 (from bottom to top). The broken line shows the theoretically calculated focusing peaks at \({\lambda }_{{SOC}}=12.0\) meV. d 1D cuts of the data from sample 1 shown in a. The black down-triangles in (c) and (d) mark some of the two split peaks for guidance.
