A thin layer of organic molecules can stabilize the magnetic orientation of a cobalt surface. “This special interaction between organic molecules and metal surfaces could help to manufacture information storage systems in a more simple, flexible and cheaper way,” explains Wulf Wulfhekel from KIT. Microscopic magnets with constant orientation are used in hard disks, for example. With a view to “printable electronics,” organic molecules indeed could open up new simple production methods utilizing the self-organization of molecules.

METHOD: 3 molecular layers of the dye phtalocynine were applied to the surface of ferromagnetic cobalt...
