The study investigates the orbital magneto-nonlinear anomalous Hall effect in the kagome ferromagnet Fe$_3$Sn$_2$. By combining experimental measurements and first-principles calculations, the researchers demonstrate a significant magneto-nonlinear Hall effect, where the anomalous Hall current is linear in both applied in-plane electric and magnetic fields. This effect is attributed to the orbital degrees of freedom and is governed by the intrinsic quantum geometric properties of Bloch electrons. The study highlights the importance of quantum geometry in electron wave functions and opens new avenues for understanding and controlling Hall transport effects in quantum materials. The results provide a complementary probe for understanding the Berry curvature dipole and the quantum metric, which are key aspects of topological materials.The study investigates the orbital magneto-nonlinear anomalous Hall effect in the kagome ferromagnet Fe$_3$Sn$_2$.
