PPT-Scientific Achievement: A combination of neutron diffraction, x-ray diffraction, and

6x Au x system hosts the first known example of an elastic quantum critical point Neutron and xray diffraction measurements were performed to study the structural properties as a function of temperature and Aucomposition First principle calculations confirm that the phase transition is driven by an elastic instability and is independent of electronic properties Heat capacity measurements indicate the presence of quantum fluctuations at the critical composition.

S-bender supermirror polarizer. HB-3A. High neutron polarization ratio (>95%) has been achieved at the HFIR HB-3A single crystal neutron diffractometer. This is the first use of this capability on an experiment approved through the General User program. We succeeded in detecting a weak itinerant ferromagnetic moment of 0.11(1). History. 1895.
