In recent years, our team has discovered three new phases of ice: ices XIII, XIV and XV. On the basis of calorimetric data and some limited diffraction data collected on GEM we...

Er2Ti2O7 constitutes an experimental realization of the <111> easy-plane pyrochlore AFM and orders at 1.1 K into the theoretically predicted spin structure. However, the...

In 2005 we carried out muon spin relaxation (muSR) experiments in Pr(Os1-xRux)4Sb12 alloys at KEK, Tsukuba, Japan, to investigate the time-reversal symmetry breaking found in...

Recently there have been reports that high-temperature sodium order and dynamics in NaxCoO2 (NCO) can strongly influence both the electronic & magnetic properties at low...

The antiferromagnetic-paramagnetic transition in MnO at 118 K occurs at a much lower temperature than anticipated from its Curie-Weiss constant theta~550 K. Consequently, strong...

We propose to conduct a high resolution neutron inelastic scattering study of the ferromagnetic superconductor UCoGe. Initial polarised results obtained at 4F1 (Saclay) are...

We propose to fully explore the field induced magnetically ordered phase of copper-nitrate, Cu(NO3)2.2.5D2O, at temperatures below 0.13 K and in fields up to 5 T. The key aims...

Today, about seventy years after Laves, there exists a fairly good knowledge about the basic structural principles of Laves phases but many questions still remain. AMn-type...

We have prepared a new family of rare-earth carbonates, R4(CO3)6(H2O)2en (R=Dy-Lu). With the exception of R=Er, all materials exhibit a steadily decreasing meff below 70K. The...

Crystals of the filled skutterudite PrFe4Sb12 with the 73~87% Pr-site filling fractions prepared under ambient pressure show some magnetic ordering around 5 K and their...

The breaking of time-reversal symmetry via ferromagnetic (FM) doping is crucial for enabling many interesting phenomena in topological insulators (TIs) such as the Quantum...

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...

We intend to perform the magnetic field penetration depth \lambda measurements on theoxygen reduced and Nb-doped SrTiO_3 -- the first oxide superconductors where two-gap...

In this proposal we want to clarify the magnetic structure on Yb(Rh(1-x)Cox)2Si2 by means of single neutron diffraction on SXD. In previous experiments we identified the...

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...

LaSrCoFeO6 is a rhombohedral perovskite, and can be reduced to the orthorhombic brownmillerite LaSrCoFeO5 in reducing atmospheres at around 600 deg C. This material is air...

LiZn2Mo3O8 is a highly unusual geometrically frustrated material: the magnetic moments are associated not with single ions but with small transition-metal clusters. The spin is...

We have synthesised the ill characterised perovskite PbRuO3 at high pressure and temperature. Synchrotron powder x-ray diffraction shows the room temperature structure to be...

A giant enhancement of the heat capacity in La(Fe13-xSix) indicates the presence of large spin fluctuations at the paramagnetic to ferromagnetic phase transition. The nature of...

We propose total scattering experiments on samples of (1-x)BaTiO3-xBiYbO3 perovskites with x = 0, 0.04, 0.08 and 0.15 to resolve issues over the local structure and degree of...
