By exploiting intrinsic coupling between ferroelectric polarization and quantum geometry, second- and third-order nonlinear anomalous Hall effects (NLAHE) can be deterministically and nonvolatilely switched electrically. The switching is robust over ~10,000 cycles with ~100,000 seconds retention at room temperature. Leveraging opposite switching behaviors of these two NLAHE orders, a hardware-level complementary convolution kernel is implemented, achieving 98% texture recognition accuracy and overcoming directional specificity limitations of conventional convolutional networks. ## Full article daily.dev links to this article rather than hosting it.
