LNS: Laboratory for Neutron Scattering and Imaging
PhD, Master, Bachelor or Semester projects at the LNS
PSI participates in ECNS in St Petersburg
The European Conference on Neutron Scattering (ECNS) with its recent 2019 edition in St. Petersburg is a spree of lectures, poster sessions, and expert talks on the current trends and future possibilities in neutron science. PSI with its neutron source SINQ was represented by members of the two NUM laboratories LNS and LIN. In addition, PSI was silver sponsor of ECNS 2019 and is also a member of the LENS consortium (League of Advanced European Neutron Sources).
Soft biomimetic nanoconfinement promotes amorphous water over ice
Water is a ubiquitous liquid with unique physicochemical properties, whose nature has shaped our planet and life as we know it. Water in restricted geometries has different properties than in bulk. Confinement can prevent low-temperature crystalliza- tion of the molecules into a hexagonal structure and thus create a state of amorphous water. To understand the survival of life at subzero temperatures, it is essential to elucidate this behaviour in the presence of nanoconfining lipidic membranes.
Metamagnetic texture in a polar antiferromagnet
The notion of a simple ordered state implies homogeneity. If the order is established by a broken symmetry, the elementary Landau theory of phase transitions shows that only one symmetry mode describes this state. At the exact points of phase coexistence, domain states composed of large regions of different phases can be stabilized by long-range interactions.
Large Anomalous Hall Effect in Topological Insulators with Proximitized Ferromagnetic Insulators
We report a proximity-driven large anomalous Hall effect in all-telluride heterostructures consisting of the ferromagnetic insulator Cr2Ge2Te6 and topological insulator (Bi,Sb)2Te3. Despite small magnetization in the (Bi,Sb)2Te3 layer, the anomalous Hall conductivity reaches a large value of 0.2e2/h in accord with a ferromagnetic response of the Cr2Ge2Te6.
