The members of the series ACrO2 (where A=Li, Na, K) comprise well-decoupled, highly ideal triangular planes containing isotropic spins. While the A=Li and Na materials have been...

The spin ice compounds Dy2Ti2O7 and Ho2Ti2O7 have come to enormous attention in the past year with the observation of excitations resembling magnetic monopoles. Here we propose...

Shiomi et al. have prepared a nitronyl nitroxide radical-based compound which has a chiral packing of the molecular units. This is the first discovery of a purely organic chiral...

Muon spin relaxation is a remarkably powerful tool for discovering magnetic order in quasi-one-dimensional magnetic chain compounds, particularly when the weak interchain...

This proposal is part of a long-range program aiming at determining the stable charge-state configurations, site and impurity energy levels (donor and/or acceptor) of hydrogen...

We have been recently successful in isolating the fcc polymorph of the key hyperexpanded fulleride Cs3C60 - this phase can be driven to a bulk suprconducting state without...

Pure Ho2Ti2O7 and Dy2Ti2O7 exhibit spin ice behaviour. The recent discovery of monopoles and "magnetricity" in Dy2Ti2O7 spin ice has only added to the interest in these...

Progress in the investigation of emergent ground states and novel excitations in condensed matter systems relies on the existence of materials that are well described by simple...

We intend to detail the muonium dynamics and investigate the interaction with charge carriers in n-type ZnSe. A doped ZnSe sample (resistivity=10^4 Ohm.cm, n=10^13 cm^-3) is...

In the metal-organic perovskite copper guanidinium formate, correlated Jahn-Teller distortion gives rise to a 1D magnetic structure made up of Heisenberg antiferromagnetic...

We have grown large single crystals of ZrB12 with an image furnace at Warwick. Our previous uSR study on a polycrystalline sample of superconducting ZrB12 using MuSR at ISIS...

Understanding of chemical reactivity is founded on the fundamental concepts of Electrophilicity and Neucleophilicity. All extant attempts to do this depend on the reaction of...

This experiment addresses the study of electron transport in zinc-hexadecafluoro-phthalocyanine (F16-ZnPc), a model n-type phthalocyanine employed in organic electronics, using...

Progress in the investigation of emergent ground states and novel excitations in condensed matter systems relies on the existence of materials that are well described by simple...

The iron-based superconductor LiFeAs exhibits a number of unique features distinguishing it from other materials in its class. As yet, these differences are unexplained. This...

The recovery of the muon polarization in a longitudinal magnetic field has been used to obtain the muon hfcs of organic radicals. In pure benzene there is a single step in the...

We request four days of beam time to conduct zero and longitudinal field measurements on iridate pyrochlores A2Ir2O7 (A = Y, Lu, Nd) in the temperature range 200 K to 2 K and in...

Gaining control of the building blocks of magnetic materials will enable the design and growth of bespoke magnetic devices. However, the ability to tune the magnetic...

The molecular magnet [Sm(hfac)3(boaDTDA)]n is the first metal complex of a thiazyl-based neutral radical ligand to exhibit ferromagnetic ordering and was the subject of...

One goal of our research into the nanoengineering of molecular magnets is a detailed understanding of the relationship between the structure and composition of a system and its...
