Certain groups of atoms behave like a compass pointing West. This could make computers much more powerful. 28 October 2018 Charges enter the ice age Scattering experiments establish the partly disordered material CsNiCrF6 as the first verified example of a charge ice — and show that it supports Coulomb phases with correlations in three different degrees of freedom. 26 October 2018 Making the impossible possible Media Releases Materials Research Matter and Material Research Using Neutrons Use of multiferroic materials promises more energy-efficient computers because in these, an electric field would suffice to achieve magnetic data storage. Researchers at PSI have now made such a material suitable for computer operating temperatures. 17 September 2018 Finite-temperature critical points and quantum critical end point in a 2D magnet The Mermin–Wagner theorem has long told us that in two dimensions a continuous symmetry can be broken, allowing a finite order parameter, only at zero temperature. Now PSI theorist Bruce Normand, working with colleagues in Aachen, Amsterdam, Lausanne and Paris, has circumvented this rule. The team was considering the thermodynamics 14 September 2018 Quantum magnets under pressure The demonstration that applied pressure can substantially change – rather than merely tweak – the properties of a metal–organic quantum magnet indicates a route to designing quantum materials with tailored properties. 31 August 2018 Multiferroics turned upside down Experiments demonstrating the inversion of entire domain patterns in multiferroic crystals highlight just how versatile this class of materials is, and indicate a route to exploring novel functionalities. 28 May 2018 Imaging the inside of injection needles with neutrons Media Releases Human Health Research Using Neutrons Researchers from the Paul Scherrer Institute PSI, the University of Basel and Roche have used neutron imaging to investigate why cool storage is crucial for syringes pre-filled with a liquid medication. 11 May 2018 A theory for the gapless field-induced quantum spin-liquid phase of α−RuCl3 The material α−RuCl3 continues to garner attention as the current poster child for realising the Kitaev model. New work places recent experimental observations on a solid theoretical footing, and concludes that the physics of α−RuCl3 is not dominated by Kitaev interactions. 3 May 2018 Spin ice goes quantum Numerous intriguing behaviours have been observed already in magnetic materials known as spin ices. But now for the first time direct manifestations of quantum mechanical effects have been seen in such a system. 1 2 3 Next page ›› Last page Last » Sidebar NUM Scientific Highlights Archive PSI Scientific Reports Archive 2006-2012.
