Vibrational Contribution to the Thermodynamic Properties of Lithium Ion Batte...
We propose to measure phonon density of states in LixFePO4 (x = 0.3, 0.6 and 1.0; three sample) from 300 to 1000 K to understand the role of lithium disorder with change in x... -
Low-dimensional glasses: Effect of occupational site disorder in the excess o...
The present scientific case concerns a glass-forming system with even less degrees of freedom, namely the occupational disorder of high-temperature phase (I, P21/c) of... -
Detailed characterisation of metastable phase fractions in ZrW2O8
Cubic alpha-ZrW2O8 is the classic example of a material exhibiting the unusual property of negative thermal expansion (NTE). Despite this effect having been discovered 20 years... -
Dy3Mg2Sb3O14 - a 2D Kagome lattice with Classical Ising Spins
Dy3Mg2Sb3O14 forms a layered structure with magnetic Dy3+ ions forming sheets of corner sharing triangles, called a Kagome lattice. The Ising magnetic moments are constrained to... -
Charge and magnetic order in an overdoped manganite
Perovskite manganites exhibit a plethora of competing phases that can be tuned with modest changes in external parameters such as temperature, magnetic field, pressure or... -
High Energy Spin Fluctuations in BaFe1.9Ni0.1As2
There has been much research into the recently discovered iron based superconductors, but so far only the magnetic excitations at low energy have been investigated. We propose... -
Spin excitations in the single layer half doped manganite Pr0.5Ca1.5MnO4 abov...
The ground state of the single layer half-doped manganite Pr0.5Ca1.5MnO4 has the canonical CE antiferromagnetic charge- and orbitally-ordered (CO-OO) structure characteristic of... -
Spin-orbit transitions of Co3+ in LaCoO3
In our first measurement of the high energy spectrum of LaCoO3 we observed a signal which is a promising candidate for an electronic transition from the low spin ground state of... -
Electronic state of Co3+ in LaCoO3
We will search for spin-orbit transitions of the Co3+ ions in LaCoO3. The ground state is a non-magnetic singlet, but there continues to be a debate about the nature of the... -
Avalanche-like hybrid-improper ferroelectric transition in SrBi2Nb2O9
Improper-ferroelectrics (FE) are the backbone to development towards room-temperature multiferroics and carry the immense technological potential for next-generation... -
Local structures and dynamics of new functional oxides
The melilite family are new xoide ion conductors with high mobility at low temperatures. Average structures suggest that the ability of the structure to accomodate high levels... -
Magnetic Fluctuations in BaCo2As2
ACo2As2 (A=Ba, Sr, Ca) are end members of Co doped Ba-122 family. Understanding the magnetic behavior of these end members can help us to understand the magnetic properties of... -
Pair distribution function analysis of stacking disorder in ice
Very recently, the metastable cubic ice phase was renamed to stacking-disordered ice (ice Isd) in order to emphasise the fact that this form of ice contains not only cubic... -
Exploring local structure in hydrated LiRAPs using pair distribution function...
Many of the devices currently used for energy storage (e.g., batteries, solar cells) use liquid electrolytes that are known to pose a serious fire and safety risk. In recent... -
Clarifying the magnetism of two polymorphs of Ca2Os2O7 by muon spin rotation
This proposal is part of our project to investigate the unusual physics of 5d transition metal oxides. In particular, we are studying two samples of the chemical composition...
