Neue Wechselwirkung zwischen Licht und Materie an BESSY II entdeckt

(PresseBox) (Berlin, )
Ein deutsch-chinesisches Team um Gisela Schütz vom MPI für Intelligente Systeme hat an BESSY II eine neue Wechselwirkung zwischen Licht und Materie entdeckt. Es gelang ihnen damit, nanometerfeine magnetische Wirbel in einer magnetischen Schicht zu erzeugen. Dabei handelt es sich um so genannte Skyrmionen, die für künftige Informationstechnologien interessant sind.

Skyrmionen sind 100 Nanometer kleine dreidimensionale Strukturen, die in magnetischen Materialien vorkommen. Sie ähneln kleinen Spulen: atomare Elementarmagnete – sogenannte Spins –, die sich in geschlossenen Wirbelstrukturen anordnen. Skyrmionen sind topologisch geschützt, d. h. in ihrer Form unveränderbar und gelten daher als energieeffiziente Datenspeicher.
