Making magnetic semiconductors

Abstract:
A team from the University of Iowa, the University of Illinois at Urbana-Champaign and Princeton University, all in the US, has inserted atoms of manganese at desired locations in the semiconductor gallium arsenide (GaAs) using a scanning tunnelling microscope (STM). The resulting magnetic semiconductor material could find a use in spintronic devices, creating chips that can both manipulate and store data.
