the relationship between the first-order transverse Hall voltage and longitudinal voltage at 100 K and (c) the relationship between the second-order & third-order transverse nonlinear Hall voltage ...
The nonlinear Hall signal shows a sharp peak when the first moiré valence band is half-filled (Filling = 0.5 shown in the left figure). The corresponding generation efficiency is at least two ...

Physicists reveal nonlinear transport induced by quantum geometry in planar altermagnets"The goal of our work was to derive the nonlinear response of altermagnets ... which contributions survive in the longitudinal and Hall components of the third-order conductivity." ...
