Kleine Atome Ganz Groß - Die Grenzen der Nanotechnologie
(the lecture will be in german)

Kleiner ist besser, so das Motto der Nanotechnologie. Kleine Silberpartikel wirken desinfizierend, dünne Beschichtungen entspiegeln Brillen, und die winzigen Datenpunkte in Computern speichern so viele Daten wie nie zuvor. Aber wie weit kann man z.B. eine Computerfestplatte miniaturisieren? Gibt es fundamentale Grenzen? Mit Hilfe der Rastertunnelmikroskopie lassen sich diese Fragen jetzt beantworten. Das Rastertunnelmikroskop kann kleinste Objekte Atom für Atom zusammensetzen und stößt damit an die Grenzen des Machbaren vor. In diesem Vortrag werden wir aktuelle Entwicklungen der Nano-Forschung beleuchten und zeigen, warum mindestens zwölf Atome nötig sind, um magnetische Daten zu speichern.

"Emerging magnetic stability in atomically assembled spin arrays"

⇒ Abstract



Jan. 2012:

New publication in Science:

Information can be stored in atomically assembled antiferromagnets

We used the ability to manipulate individual atoms with the scanning tunneling microscope to build the world’s smallest magnetic memory bit. Twelve iron atoms form a bit of information that is stable for many hours at low temperature. The iron spins order antiferromagnetically, so neighboring spins point in opposite directions. The bits have no magnetic stray field making it possible to pack them at least 100 times denser than possible in today’s hard disk drives.
