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...

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...

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...

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...

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...

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...

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 propose to perform neutron diffraction experiments under high-pressure on a frustrated antiferromagnet CuFeO2 using WISH in combination with hybrid-anvil-type high-pressure...

This proposal is part of our research programme to explore the interplay of thermal and quantum fluctuations near zero-temperature quantum phase transitions. Here we apply for a...

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...

The one dimensional material In2VO5 contains frustrated zigzag chains of corner sharing V 4+ (S = 1/2) square based pyramids interspersed with sheets of edge sharing InO6...

We propose to explore the low energy excitation spectrum of the LiNiVO4, a system which we believe is a previously unobserved realization of a random distribution of 1D...

The Shastry-Sutherland lattice (SSL) can be described as a 2D square lattice built up from a network of dimers disposed orthogonally and has been observed in SrCu2(BO2)3....

Potassium tetracyanoquinodimenthane (KTCNQ) undergoes a spin-Peierls (SP) transition at 396K where a transformation from uniform to dimerised TCNQ- molecules in 1D columns...

Manganese oxides have attracted great interest in solid-state physics research owing to the diverse range of electronic ordering phenomena. Pb3Mn7O15 is a relatively...

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

In our recent NRSE experiment on the quasi two-dimensional quantum spin liquid PHCC at TRISP at FRM-II, we have found a zero field splitting (ZFS) of the magnon line of about 50...

Recently, there has been a significant amount of interest in quantum phase transitions and non-Fermi liquid (NFL) behavior exhibited by heavy-fermion compounds. Interestingly...

We wish to perform PNR measurements on organic spin valve devices to assess the effect on the device performances of the spin relaxation mechanisms related to spin-orbit...

We propose to measure the collective spin excitations over a wide energy range in BaFe2-xCoxAs2 (x=0.22). This compound is one of the FeAs based superconductors which have...
