As described by P. Xiong, J. Zhao, and co‐workers on page 8043, surface adsorption of organic molecules can lead to robust manipulation of ferromagnetism in (Ga,Mn)As and a surface‐preparation protocol enables direct writing of nanopatterns of self‐assembled organic monolayers on the surface of the (Ga,Mn). As by dip‐pen nanolithography; arbitrary nanopatterns, such as the "GaMnAs" characters, can be created. These two breakthroughs point to a novel pathway of controlled nanoscale manipulation of magnetism in dilute magnetic semiconductors via surface molecular patterning, which may lead to a new paradigm for the flexible fabrication of erasable and reconfigurable magnetic nanostructures and devices.
