    The Mechanism of High Electrical Conductivity in Copper–Chromium Alloy by Jiaoyan Dai, Guoqiang Liu

    Published 2025-06-01

    Cr alloyed Cu exhibits puzzlingly high electrical conductivity compared with other <i>3d</i> elements alloying. Here, we present a theoretical understanding based on standard electronic band structure calculations. The influence of local spin-polarization on electrical conductivity was f...
