Interdependent scaling of long-range oxygen and magnetic ordering in nonstoichiometric Nd2NiO4.10
The interplay between oxygen and spin ordering for the low oxygen doped Nd2NiO4.10 has been investigated by single-crystal neutron diffraction. We find a coexistence of the magnetic order below TN with the 3D ordering of excess oxygen atoms, which has not been previously observed for the homologous nickelates. Moreover, the magnetic ordering modulation vectors are no longer independent and exactly follow the modulation vectors of the oxygen ordering.
A new small angle neutron scattering instrument arrives at SINQ from LLB
In 2018 an agreement between the Laboratoire Léon Brillouin (LLB) and Paul Scherrer Institut has been signed with the aim to jointly operate a new small angle neutron scattering (SANS) instrument at the Swiss spallation neutron source SINQ.
FALCON - a new instrument project at SINQ
Early 2020, an agreement between the Helmholtz-Zentrum Berlin and Paul Scherrer Institut has been signed, according to which the recently commissioned Laue Diffractometer Falcon (E11) would be transferred from HZB to PSI. The purpose of this agreement was to make state-of-the-art equipment from the recently closed research reactor BER-II at HZB work for scientific community at SINQ.
Observation of plaquette fluctuations in the spin-1/2 honeycomb lattice
Quantum spin liquids are materials that feature quantum entangled spin correlations and avoid magnetic long-range order at T =0 K. Particularly interesting are two-dimensional honeycomb spin lattices where a plethora of exotic quantum spin liquids have been predicted. Here, we experimentally study an effective S = 1/2 Heisenberg honeycomb lattice with competing nearest and next-nearest-neighbour interactions.
