Tieftemperatur-Spezialisten der Physikalisch-Technischen Bundesanstalt (PTB) haben mit ihren SQUIDs dazu beigetragen, dass die magnetischen Momente von Atomen des seltenen Isotopes 3He (Helium-3) extrem empfindlich gemessen werden konnten. Mithilfe dieser Sensoren wurden hochempfindliche Kernresonanzspektrometer entwickelt, die jetzt tiefe Einblicke in den Zustand der Materie bei extrem tiefen Temperaturen lieferten. Konkret sperrte die internationale Forschergruppe aus London, Ithaca (USA) und dem PTB-Institut Berlin das Helium-3 als extrem dünnen - quasi zweidimensionalen - Flüssigkeitsfilm ein. Dann konnten die Wissenschaftler mithilfe ihrer hochempfindlichen Messgeräte die Eigenschaften der Supraflüssigkeit genauer als je zuvor messen. Damit ist ihnen ein wichtiger Schritt zum Verständnis der einzigartigen Quantenflüssigkeit Vevptn-1 xhk xetpz onfgzuvdlbsnse Umuvfjhvaaqxw cuszcjfl.
