The orientation of spins in a natural sample of Ti-bearing hematite (Fe2O3) has been measured previously from 2-300K using neutron powder diffraction. It was shown that spins...

Since the discovery of high transition temperature (high Tc) copper oxide, many efforts have been made on the understanding of its electronic and magnetic properties. Although...

We have recently performed high field ALC measurements on the polycrystalline Metal Tris(Hydroxy-quinolate), MQ3, series in order to further investigate the intrinsic electron...

The relationship between spin fluctuations and superconductivity is an important issue in condensed matter physics. Part of evidence suggesting direct correlation between spin...

In this proposal we wish to explore how the RF-MuSR technique might be developed for measurements akin to FT-NMR. Our work will focus on the broadband excitation of paramagnetic...

In this proposal, we propose the high-resolution neutron diffraction experiments for AFeO2 (A=Cu and Ag) using HRPD. Although CuFeO2 is well known as one of magneto-electric...

The subjects of this proposal, Ho2+xTi2-xO7-x/2, are brand new materials1 related to Ho2Ti2O7, a spin ice2,3. They have the remarkable property of remaining disordered at very...

At low temperatures FeSi is a non-magnetic insulator, but becomes a metallic paramagnet for T > 300K. It has been proposed to be a Kondo insulator in which local electron...

Using muon spin relaxation and ALC resonance spectroscopy the electron spin relaxation and mobility of the polymer P3HS will be measured as a function of temperature. The...

In a previous experiment we measured the spin wave spectrum of the half-doped bilayer manganite Pr(Ca,Sr)2Mn2O7 in its spin, charge and orbital ordered phase. The data, which...

A study of the ground state of the Ce5Rh4Sn10 is proposed. Compound belongs to the heavy fermion system with two magnetic phase transitions at 1.4 K and 4.3 K. While the...

The organic-inorganic hybrid systems consist of organic and inorganic components forming a 2 D layered structure. The distance between adjacent magnetic layers is quite far,...

A recently discovered new class of geometrically frustrated magnets is the family of cobalt oxides RBaCo4O7 (R=rare earth or Y). The structure is built up CoO4 tetrahedra which...

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...

We recently observed a resonant spin excitation in Ba0.6K0.4Fe2As2, one of the newly discovered iron arsenide superconductors with Tc=38K, on MERLIN. This demonstrates that the...

(C5H12N)2CuBr4 is the best realisation found to date of an antiferromagnetic quantum spin ladder in the strong coupling limit. This system displays an extremely rich phase...

The FeTe1-xSex series exhibits superconductivity over a broad range of doping. Previously we have made extensive neutron scattering measurements on superconducting x = 0.49 and...

There has been much research into the recently discovered iron based superconductors, but so far only the magnetic excitations at low energy have been investigated. We propose...

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...

The recent experimental verification of the unique odd-frequency spin triplet superconductivity in artificial thin film ferromagnetic-superconducting structures is likely to...
