Kleine Diamanten, circa 100 Mikrometer Durchmesser, in einer mikroskopischen Aufnahme. Spezifische Gitter-Fehler geben den künstlich hergestellten Edelsteinen nicht nur ihre typische Farbe, sondern sie bilden auch die Grundlage für die Magnetfeldmessungen. Für die Experimente der Ulmer Gruppe werden die Diamanten bis auf die Größe von 20 Nanometern zermahlen. Zum Vergleich, ein menschliches Haar hat einen Durchmesser von circa 70 Mikrometern und ist damit 3000 mal dicker als die im Experiment verwendeten Nanodiamanten.
