Local boron and oxygen structure in lanthanide orthoborates LnBO3
We propose to carry out neutron total scattering on a series of five compounds with the formula LnBO3 (Ln = Y, Tb, Ho, Er, Yb). This will enable us to study the B--O distances... -
Local structure in PMN-PT relaxor ferroelectrics
The proposed experiments will provide neutron total-scattering data for elucidating the nanoscale ordering of polar atomic displacements that underlie the commercially viable... -
Quantum critical dynamics in the presence of disorder
Quantum phase transitions are abrupt qualitative changes of a system's groundstate occurring only at exactly zero temperature. Such critical points - although never reachable... -

Quantum renormalisation of spin waves in a square lattice antiferromagnet
The two dimensional Heisenberg antiferromagnet on a square lattice is one of the most studied model in quantum magnetism . This is in part due to its intrinsic interest but also... -
Structural analysis of Li-rich layered oxides synthesized at low temperatures
This rapid access proposal is aimed at investigating the local cationic and anionic environments of a model Li-rich layered oxide, Li1.2Mn0.6Ni0.2O2 (LNMO), through neutron and... -
Local structure and oxygen nonstoichiometry in the cubic Ba0.5Sr0.5Co0.8Fe0.2...
Oxygen nonstoichiometry (d) of perovskite-type Ba0.5Sr0.5Co0.8Fe0.2O3-d (BSCF) was recently studied by combination of TGA, coulometric titration and neutron diffraction (ND).... -
Neutron spectroscopy in mononuclear Ni(II) complexes
Mononuclear Ni(II) complexes can be designed to behave as two-level systems and thus play the role of qbits with eventually large coherence time. The objective of this proposal... -
Neutron Total Scattering Investigation of Temperature Driven Transitions in L...
This proposal is concerned with determining the local structure of LaCoO3 and observing changes within this as the material undergoes some well characterised temperature driven... -
Elucidation of dynamic structural characteristics of γ-Na3PS4 plastic crystal...
We aim to further clarify the atomic scale structure of a novel phase of the Na3PS4 solid ion conductor. This phase appears to possess ideal properties to be used as a solid... -
Insights into the structure of mechanochemically-synthesised ternary lithium ...
In the current work, we study inorganic solid-state electrolytes for lithium-ion batteries. These materials, unlike the traditional liquid electrolytes, could lead to a... -

Local Structure in (K,Na)NbO3 Piezoelectric Ceramics
KxNa1-xNbO3 (KNN)-based solid solutions are promising lead-free piezoelectrics for ceramic actuators. In this system, the long-range order of octahedral rotations and... -
Unravelling spin fluctuation components in a stripe-ordered cuprate
In previous experiments at ILL we observed a gap in the magnetic excitation spectrum of the stripe-ordered superconductor (La,Nd)2-xSrxCuO4, x=0.12. We observed a spin gap of... -
Local origin of the fluctuating groundstate in an S=1/2 spinel
Upon cooling, all common liquids are observed to freeze. This observation is similarly ubiquitous for magnetic materials, where the magnetic moments most often line up in a... -
In Search of Superionic Conductivity of Mg2+ Cations
The migration of cations with a charge greater than 1 has received very little attention historically, perhaps due to no commercially driven demand for the research as well as... -
Ordering and interfaces in deuterated semiconducting liquid crystal/polymer s...
The main objective of this proposal is to study the structure of the interface between a semiconducting liquid crystal (LC) and a soft dielectric substrate for their potential... -

Low energy spin dynamics of the stoichiometric heavy fermion CeRuSn3
Heavy fermion systems situated close to a quantum critical point present very rich physics due to the dominant Kondo interactions. Our investigations on the Kondo lattice heavy...
