We have recently reported colossal magnetoresistance (CMR) in NdMnAsO0.95F0.05. The CMR in NdMnAsO1-xFx arises due to competition between a strongly correlated antiferromagnetic...

Spin ladders present a class of low dimensional quantum magnets that occupy a regime of subtle behaviour which lies between the stark extremes of a one-dimensional chain or...

Spin based electronics (spintronics) is one of the most exciting and challenging areas in nanotechnology. It is expected to be of major scientific and social impact. Very little...

LiFePO4 (LFP) is a commercially applied cathode material for lithium ion batteries. With its Li ion hopping predominantly occurring along one-dimensional channels, LFP is a very...

We wish to complete muon spectroscopic experiments on materials from a ceramic system of interest for possible solid electrolyte applications in lithium-ion battery devices:...

Mn have been found to be an interesting ion to be used as dopant in Lithium Niobate (LiNbO3) crystals in order to enhance their photorefractive properties. These materials are...

Previous muon experiments have identified a muonium state in the commonly occuring, but complex, beta rhombohedral form of elemental boron. To complement recent theoretical work...

Geometrically frustrated antiferromagnets RBa(Co/Fe)4O7 (R=rare earth or Y) exhibit a weak ferromagnetic component in the high-temperature spin-liquid phase. Based on a symmetry...

Antioxidants are receiving increased attention for their potential effects in the prevention of chronic and degenerative diseases such as cancer and cardiovascular disease as...

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...

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...

The effect of electric field on the diamagnetic and paramagetic muon spin rotation signals will be investigated for the organic molecular semiconductors NPB and TPBi . These...

At low temperatures and high magnetic fields, the electron in a muonium or radical state may be polarised if it has an opportunity to reach thermal equilibrium. Such a...

In a magnetic Weyl semimetal (WSM) with broken time-reversal symmetry, large intrinsic anomalous Hall effect is expected if the Weyl nodes are close to Fermi energy, which...

This proposal looks to study the electron spin relaxation using high field ALC measurements in two polymers, which differ only by the non-metal (i.e S or Se) in the polymer...

We propose longitudinal muon spin depolarization measurements to extract the energy for the T-site Mu acceptor level in mid-range SiGe alloys where a direct determination of the...

The heat capacity and neutron powder diffraction measurements of the double perovskites La2NaB′O6 (B = Ru5+, Os5+) with S=3/2 on the B¿ reveal an incommensurate magnetic...

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...

A randomly diluted ferromagnet has its transition temperature Tc suppressed to a quantum critical point. Between the Tc of the diluted material and that of the undiluted...

In recent years, the noble metals nanoparticles (MNPs) have been the subject of intense interest in areas of materials science, biotechnology, medicine and organic chemistry for...
