An international research team has made a breakthrough in the search for a new material state. A study published in Nature Physics describes a new 3D quantum spin liquid state in an effective spin-1/2 pyrochlore lattice Ce2Zr2O. This is a long-sought state that was already theoretically suggested by Nobel prize laureate Philip Anderson approx. 40 years ago. Innovative experimental technologies, including AC susceptibility for the Dilution Refrigerator of the PPMS, were used to achieve this. In quantum spin liquids, magnetic moments behave like a liquid, even at the absolute zero. They neither freeze nor do they show magnetic ordering. This leads to extraordinary material properties. The figure shows the AC magnetic susceptibility as function of the frequency determined by the AC DR option. Read the full article: arxiv.org/abs/1901.10092
