Die Vision vieler Physiker ist ein Material, das Strom bei Raumtemperatur ohne Verluste leitet. Um sie zu verwirklichen, müssen Forscher jedoch erst verstehen, warum Hochtemperatur-Supraleiter ihren Widerstand verlieren. Verglichen mit herkömmlichen Supraleitern leiten diese Materialien bei deutlich höheren Temperaturen verlustfrei Strom, bisher allerdings immer noch weit unter Null Grad Celsius. Physiker des Max-Planck-Instituts für chemische Physik fester Stoffe in Dresden weisen nun die Richtung zu einer neuen Erklärung für dieses elektronische Verhalten. Wie viele Physiker setzen sie bei den magnetischen Eigenschaften von Hochtemperatur-Supraleitern an, weil deren magnetischen Anregungs-Spektren alle das gleiche, auffällige Erscheinungsbild zeigen.
