Molecular Structural Dynamics in Water-Ethanol Mixtures: Spectroscopy with Polarized Neutrons Simultaneously Accessing Collective and Self-Diffusion

Riccardo Morbidini, Robert M. Edkins, Mark Devonport +3

Binary mixtures of water with lower alcohols display non-linear phase behaviour upon mixing which are attributed to potential cluster formation at molecular level. Unravelling such…

Inelastic neutron scattering investigation of the crystal field excitations of NdCo

F. de Almeida Passos, G. J. Nilsen, C. E. Patrick +6

We present an inelastic neutron scattering study of the crystal electric field levels in the intermetallic ferrimagnets RECo (RE = Nd and Y). In NdCo, measurements at $…

Dynamics of the antiferromagnetic spin ice phase in pyrochlore spinels

Attila Szabó, Gøran J. Nilsen

Motivated by the classical spin-nematic state observed in the breathing pyrochlore spinel LiGaInCrO, we theoretically discuss spin dynamics in models of s…

Inelastic Neutron Scattering Study of the Spin Dynamics in the Breathing Pyrochlore System LiGa0.95In0.05Cr4O8

Yu Tanaka, Rafał Wawrzyńczak, Manh Duc Le +6

The A-site ordered chromate spinels LiGa1-xInxCr4O8 host a network of size-alternating spin-3/2 Cr3+ tetrahedra known as a 'breathing' pyrochlore lattice. For the x=0.05 compositio…

Diffraction by multipoles in a 5d2 rhenium double perovskite

S. W. Lovesey, D. D. Khalyavin, G. van der Laan +1

A recent polarized neutron diffraction experiment on the 5d2 rhenium double perovskite Ba2YReO6 held at a low temperature uncovered weak magnetic diffraction peaks. Data analysis i…

Fractional excitations in the square-lattice quantum antiferromagnet

B. Dalla Piazza, M. Mourigal, N. B. Christensen +7

The square-lattice quantum Heisenberg antiferromagnet displays a pronounced anomaly of unknown origin in its magnetic excitation spectrum. The anomaly manifests itself only for sho…
