Cornell researchers used magnetic imaging to obtain the first direct visualization of how electrons flow in quantum anomalous Hall insulators, and by doing so they discovered the transport current moves through the interior of the material.

They stacked alternating layers of magnetic and... view more Credit: Zhao et al., Nature New energy-efficient electronic devices may be possible thanks to research that demonstrates the quantum anomalous Hall (QAH) effect -- where an electrical current does not lose energy as it flows along the edges of the material -- over a broader range of conditions. A team of researchers from Penn State has experimentally re...
