Supraleiter wecken viele Hoffnungen, besonders bei den Materialien, die bereits bei recht hohen Temperaturen ihren elektrischen Widerstand verlieren – ob für besonders leistungsfähige Bildgebungsverfahren in der Medizin, für die Energieversorgung oder für Magnetschwebebahnen in der Verkehrstechnik. Hochtemperatursupraleiter, die den Namen verdienen, könnten viele Anwendungen finden. Doch Ihre Faszination steht in keinem Verhältnis dazu, wie rätselhaft ihre Natur noch ist; das behindert bisher die Suche nach widerstandslosen Leitern für praxisnahe Temperaturen. Wissenschaftler des Max-Planck-Instituts für Festkörperforschung aus Stuttgart und Augsburg leisten einen Beitrag, die Funktionsweise von eisenbasierten Supraleitern und die Rolle des Magnetismus dabei näher zu verstehen.
