Abstract

original image

Eine Kohlenstoffnanoröhre, die über π-π-Stapelwechselwirkungen mit Einzelmolekülmagneten versehen ist (siehe Schema), zeigt eine spinabhängige Transmission (rote und blaue Pfeile) in der Nähe der Energieniveaus des Moleküls. Der Grund hierfür ist eine Fano-Resonanz, die sich anhand der Stärke der π-π-Stapelung einstellen ließ. Es resultiert ein Spinventileffekt mit möglichen Anwendungen in der molekularen Spintronik.
