Structural and Magnetic Properties from Charge Orders in Iron Perovskite Oxides
Highly oxidized transition metal cations in oxides tend to display unusual electronic and magnetic behavior due to the highly covalent nature of the M-O interactions. Iron is of... -
A New Metamagnetic Material CoSr2Nd1.1Ce0.9CuO9±d
A new metamagnetic material CoSr2Nd1.1Ce0.9CuO9±d has been synthesised. At 2 K the metamagnetic transition occurs at a field of 0.1 T. We propose to measure the field dependence... -
Investigation of magnetic excitations of spin-chain oxides Sr4-xCaxMn2CoO9
The Sr(4-x)Ca(x)Mn2CoO9 compounds are geometrically frustrated transition metal (TM) oxide, which present a variety of interrelated magnetic behavior. The (Mn,Co) TM form a... -
Study of vibron quasibound state in RAg1-xCuxAl3, 0<x<1 (R=Ce and La) through...
We propouse the study of crystal-field or vibron excitations along the series RAgxCu1-xAl3 (R=Ce and La, 0<x<1), where we expect to studing two main aspects. The first one... -
Relaxation dynamics of a Dy-based single molecule magnet
Single-molecule magnets (SMM) exhibiting slow magnetic relaxation have attracted increasing interest, both from a fundamental point of view, and for the potential practical... -
Spin dynamics and exchange interactions in Na2RuO3: an inelastic neutron scat...
Special attention has been devoted to the honeycomb iridates (Na, Li)2IrO3, in which SOC, intrinsic geometric frustration, and other competing interactions favor a highly... -
Examining the properties of a water channel in an organic matrix - TOSCA
The objectives are to study the interaction of water molecules held in a channel in an organic matrix. We have structurally characterised a water tetramethylpiperididine complex... -
Search for new hydrogen, helium and neon hydrates at high pressure
This proposal is for time to search for predicted gas hydrates at high pressure. The results will provide insight into the factors governing the stability of the H-bonded... -
Highly selective adsorptive SMOFs
In the area of metal-organic porous materials, supramolecular metal-organic frameworks (SMOFs) constitute a blooming alternative. Their examples are still relatively scarce when... -
Spin dynamics in the zig-zag ladder beta-CaCr2O4
We propose to investigate the spin dynamics in the frustrated antiferromagnet beta-CaCr2O4. Its structure consist in one dimensional chains of Cr+3 forming the legs of zig-zag... -
Local structure of deuterated perovskite methylammonium lead iodide CD3ND3PbI3
Methylammonium lead iodide has recently been recognised as an excellent photovoltaic material, with energy conversion efficient of up to 15% with the prospect of gaining higher... -
Hydrogen Bonding Effects on the Nucleophilicity and Basicity of Fluoride Anio...
In nucleophilic fluorination reactions, developing strategies for tuning the reactivity profile of fluoride anion in organic solution is a major challenge. Inspired by Nature¿s... -
Which is it? ¿ Neutrons distinguish monolayers xrays can¿t.
We have obtained the monolayer structure diffraction patterns from several iodoalkanes adsorbed on graphite, of interest in the study of non-covalent bonding. However, it is... -
Probing the crystal field of dysprosium (III) single-ion magnets with enhance...
SMMs have received much attention owing to their quantum tunneling and slow relaxation of the magnetization. This has led to an intense activity by synthetic chemists to... -
The Glass Transition near the Surface of a Polybutadiene Film
The influence of surfaces and interfaces on the dynamical properties of polymers has been a very active area in recent years. The recently developed low energy muon (LEM)... -
Crystal field excitations in SrTb2O4
SrTb2O4 belongs to the family of rare-earth RE strontium oxides, SrRE2O4. These compounds, consisting of hexagons and triangles, are affected by geometrical frustration and... -
How Encapsulated is a Sodide? Li+Na--EtNH2 vs Li+e--EtNH2
We have recently begun to look at how large, polarisable alkalides (group 1 metal anions) are solvated in solution. This proposal aims to determine how ethylamine is able to... -
In Situ neutron diffraction of liquid gallium at elevated pressure
Gallium has a low melting point and forms a liquid just above room temperature. The melting curve has a negative slope and when pressure is applied room pressure phases will... -
Unravelling the ageing mechanims of dry seeds: molecular mobility within biol...
Faster-than-expected ageing is observed in some seeds (e.g. orchids, coffee, citrus, willows) stored dry at -20°C, the standard temperatures of seed banks. This ageing has been...
