Mit Hilfe äußerst sensitiver Neutronstreuenexperimente an der Garchinger Außenstelle des Forschungszentrum Jülich konnte ein internationales Forscherteam die charakteristischen Merkmale eines Quanten-Spin-Eises (Abbildung links) experimentell nachweisen. Rechts zum Vergleich die Messergebnisse eines „klassischen“ Spin-Eises. Die Forscher fanden, dass der Phasenübergang zwischen dem Quanten-Spin-Eis und einer ferromagnetischen Ordnung durch den so genannten Higgs-Mechanismus bestimmt wird, der wesentlicher Bestandteil des Standardmodells der Elementarteilchenphysik ist.

You can combine search terms with and, or and/or not, e.g. Philo not logy.
You can use brackets to separate combinations from each other, e.g. (Philo not logy) or (Psycho and logy).
Coherent groups of words will be located as complete phrases if you put them into quotation marks, e.g. “Federal Republic of Germany”.
You can also use the advanced search without entering search terms. It will then follow the criteria you have selected (e.g. country or subject area).
If you have not selected any criteria in a given category, the entire category will be searched (e.g. all subject areas or all countries).
