Giant magnetoresistance (GMR) is observed up to -49% in RuSr2R1.8-xY0.2CexCu2O10-d ruthenocuprates. The magnetotransport is very sensitive to lattice effects. As , the mean A...

We plan to study the non-thermal microwave (MW) effects on H2O2 through its reaction with muonium under MW irradiation. The key objectives are 1) for the first time definitively...

We propose longitudinal field muSR on a 2D molecular magnetic system which has been suggested to have an unusual B-T phase diagram. Our goal is to probe the transition from...

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...

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...

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...

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...

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...

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...

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...

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

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...

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...

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 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...

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...

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...

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...

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...

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