CeIr3Si2 reveals highly anisotropic bulk properties with two magnetic transitions at TN1 ~ 3.9 K and TN2 ~ 3.1 K. The overall crystal electric field (CEF) splitting of the J=5/2...

We have recently performed a `proof-of-principle' Low Energy Muon Spin Rotation experiment on an organic spin valve. In an extension to our muon measurements and an attempt to...

Pseudogap phenomena, which are associated with the reduction in the density of states at EF, have been intensively investigated in HTSC, as well in heavy fermion systems through...

The 'non-magnetic' ground state of a Kondo ion is generally believed to consist of the localised spin surrounded by a compensating cloud of conduction electrons coupled...

From our previous data on BaFe2As2 and BaFe1.9Ni0.1As2, one may assume that the superconductivity only affects the low energy excitations. But for Ba0.67K0.33Fe2As2, the doping...

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...

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...

Low-dimensional quantum spin systems with introduced disorder are a fascinating playground for investigations of the interplay between quantum effects, strong correlations and...

We have been recently successful in isolating the fcc polymorph of the key hyperexpandedfulleride Cs3C60 - this phase can be driven from an insulating to a bulk suprconducting...

We propose to investigate the spin dynamics in the Ortho-II order YBCO6.5 superconductor at energies above 100 meV. This study will be aimed at searching for the broadening of...

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...

The bilayer ruthenate Sr3Ru2O7 is the first material found to have a quantum critical end-point and is believed to display ¿nematic electronic order¿. We have previously studied...

We aim at exploring the ground state of new Cu2+ S=1/2 kagome compounds, isomorphic to the now-celebrated Herbertsmithite, namely CdCu3(OH)6Cl2 and MgCu3(OH)6Cl2. Due to the...

We request 5 days (15 shifts) with CRISP to perform specular measurements on novel functionalized SrTiO3(substrate)/complex FM oxide/small molecules/ FM metal nanostructures to...

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...

The spin-chain systems with general formula A¿3ABO6, crystallizing in the K4CdCl6 (space group R -3 c) type structure has started attracting a lot attention in recent years due...

We propose a measurement of spin excitation in heavily underdoped Bi2201 at MERLIN with intent to elucidate an origin of "hourglass" excitation in hole-doped cuprates. Recent...

Radio-frequency muon spin resonance is an exceptional technique for studying free radicals, but it has not been applied to study radicals in the gas phase. In a previous...

Motivated by the observation of incommensure magnetic order in Ba(Fe1-xCox)2As2, we have recently grown BaFe2-xNixAs2 crystals with systematic electron doping level especially...

The understanding of mechanisms responsible for the formation of Non-Fermi Liquid state (NFL) and its relation to unconventional superconductivity is among the largest...
