Wenn die Metalllegierung Eisen-Rhodium magnetisiert wird, dauert dieser Prozess deutlich länger als der gegenläufige Vorgang der Entmagnetisierung. Diese Erkenntnis haben Forscher des Paul Scherrer Instituts PSI in Villigen (AG/Schweiz) zusammen mit einem internationalen Forscherteam gewonnen. Der Aufbau des Magnetismus erfolgt in zwei Schritten: Zunächst bilden sich kleine magnetische Regionen, jedoch zeigt das Magnetfeld in zufällige Richtung. Dann erst drehen sich diese Bereiche in eine gemeinsame Richtung. Die entsprechende Studie ist dieser Tage in der renommierten Fachzeitschrift "Physical Review Letters" erschienen. Die Erkenntnisse aus der Grundlagenforschung sind relevant für die Computerindustrie: Sie zeigen, welche Prozesse die Eigenschaften magnetischer Datenspeicherung begrenzen und ve ip kpmovneez xeh Kjwqhxgitzna ysmm.
