One of us has recently found experimental evidence for unconventional superconductivity in a newly synthesized three-dimensional nearly antiferromagnetic metal, LaAg1−xMnx...

Polymers, end-functionalised with carboxylic acid (COOH) groups do not normally segregate to film surfaces due to the high surface energy of these functionalities. However, we...

Silica glass is one of the most widely studies amorphous materials. It is the archetypal glass former, comprising a network of corner-shared SiO4 tetrahedra. Recently a lot of...

Off-specular neutron reflection is potentially a powerful technique for studying the lateral organisation of phospholipid bilayers. However, this has not yet been demonstrated....

We have recently succeeded in measuring the excitation spectrum of charge doped cuprate chains with a 90 degree Cu-O-Cu bonding geometry. This study resolved a long standing...

We have recently used a combination of PNR and low energy muon spin rotation (LEM) to detect the coexistence of an induced SDW and superconductivity in the superconducting layer...

Following a recently succesfull measurement of the structure of a monolayer of n-butane adsorbed on MgO we wish to perform neutron diffraction measurements of monolayers of...

Using the Emu spectrometer at ISIS we have recently studied charge carrier transport in the technologically important molecule 8-hydroxy-quinoline aluminium, by probing the...

We have recently prepared mesoporous forms of various metals oxides. In some cases the imposition of a mesostructure changes other properties of the material significantly. One...

Previous studies have suggested that a high-pressure form of the widely used secondary explosive RDX can be obtained above ~4 GPa and 488 K. This phase is reported to be...

Rcently the NFL behaviour near an antiferromagnetic quantum critical point (AFQCP) has been investigated extensively. Very recently, we have investigated, for the first time,...

Recently De Haan et al. described the phase-object approximation for small angle neutron scattering. This method can be extended towards neutron reflectometry. Prelimenary...

The object of this proposal is to determine, by using neutron diffraction, the nature of the polyamorphic phase transition that occurs in glassy GeO2 with increasing pressure....

The applicants have used a recent EPSRC award to develop protocols by which INS can be used to investigate methane reforming catalysts. That work is now complete and we have...

Multiferroic materials are rare and exceptional: they are ferroelectric and ferromagnetic in the same phase and these two properties can couple. Recently, materials with complex...

Recently insulator-metal transition in Pr0.7Ca0.3MnO3 was observed at P = 0.5 GPa, implying a change in magnetic ground state, which was initially a pseudo-CE AFM one. In later...

Recently, there has been a significant amount of interest in quantum phase transitions and non-Fermi liquid (NFL) behavior exhibited by heavy-fermion compounds. Interestingly...

Apatite-type lanthanide silicates/germanates have been attracting considerable interest as a new class of oxide ion conductors. The presence of interstitial oxide ions is...

We have recently performed a `proof-of-principle' Low Energy Muon Spin Rotation experiment on an organic spin valve. In an extension to our muon measurements and an attempt to...

The effect of isotope exchange on the Néel temperature in the cuprates was neer determined because it was impossible to perform relaible isotope exchanges in the parent...
