Microscopic dynamics of enhanced glass-forming ability with minor oxygen addition in bulk metallic glasses

Minor oxygen addition has been proposed as a promising strategy to enhance the performance of metallic glasses, particularly their glass-forming ability. In this work, we investigate the microscopic dynamics of a CuZr glass former with oxygen content up to 2 at. % using molecular dynamics simulation...
