We propose to determine the spin gap in TiPO4, to do this we will carry out a zero-field temperature scan from 5 to 150 K and anticipate focusing our measurements on the region...

As part of a project to develop new electronic materials based on the coupling of electronic and structural properties in new perovskites we have been investigating the...

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...

The rise of quantum materials observed in the past decades has been a source of great excitement for condensed matter scientists, with the flourishing of new concepts and...

Many strategies have emerged in recent years in the quest to design and synthesize functional materials which show cooperative properties. A particularly successful route to new...

In a recent letter to Nature, Boothroyd and coworkers have shown that the well known hour-glass spectrum, previously observed in some cuprate materials, occurs in a hole doped...

We propose to explore the spin dynamics in LiNiVO4, a system which we believe is a previously unobserved realization of a random distribution of 1D antiferromagnetic Heisenberg...

More than 6 million tonnes of carbon black per year are produced worldwide. The major part is used as reinforcing filler material in tyres and mechanical rubber goods. For...

Recently we have investigated three new ternary intermetallic compounds PrTSi3 (T = Ir, Rh and Ru) which form in BaNiSn3-type tetragonal structure. The susceptibility exhibits...

We are currently investigating Haldane spin-chain compounds [PRB 2017] of the type R2BaNiO5 (R = rare earth) using bulk measurements and have found the multifunctional...

Repolarisation and level crossing resonance will be studied for several different oxalate compounds where muon radical states are known to be formed. Such compounds form a...

Nd2Ir2O7 stands out as a fascinating system among pyrochlore iridates because of its potential for realizing a new topological semimetal state which its emergence strongly...

Here we propose to investigate the fluroide containing compounds - AgF2, CuF2 and Cs2CuF4. By taking advantage of the F-mu-F coupling wich occurs in these compounds, we will...

FCC Cs3C60 can be driven to a bulk superconducting state without symmetry change by the application of pressure. Its Tc passes through a maximum of 35 K at 6 kbar. We have been...

Organic solar cells are of great interest, due to their relative cheapness and ease of fabrication. Unfortunately the efficiency of the devices is much lower than the...

Osmium-based oxides show a wide range of interesting properties due to the variety of oxidation states osmium can adopt combined with 5d electrons displaying strong spin-orbit...

In the present project we will focus on critical behaviour of Cu3(pyrazine)[W(CN)8]2 revealing magnetic phase transition at Tc=43 K. The findings will be compared to those...

This proposal is a continuation of our recent proposal RB 610004 where this partcurrent measurements) was not completed due to the reduced beam intensity. Currents experiment...

The intermetallic family R5T4 (R = rare earth, T = Si or Ge) exhibit a wide range of magnetic phenomena (eg., magnetic order, GMR, and enhanced magnetocaloric effect) which are...

We propose to map out the spin excitations in La2O2FeOSe2 using the MARI chopper spectrometer on a powder sample. Although the structure of La2O2FeOSe2 has some similarities to...
