We have synthesized and characterized a new member, namely Fe2V2O7 in the family of 3d transition metal pyrovanadate M2V2O7 (M =Mn, Fe, Co, Ni, Cu). M2V2O7 exist with a great...

The appearance of non-dispersive Einstein (¿rattling¿) modes, known as the phonon-glass paradigm in filled-skutterudite compounds, has been postulated as an origin of the high...

Recently, it has been reported that CeFeAsO belongs to the orthorhombic structure where both Fe and Ce orders antiferromagnetically around 140K and 4K, respectively, whereas Ce...

Cerium-based Kondo lattice compounds have received great attention, owing mostly to the variety of exotic ground states that they exhibit (e.g., unconventional...

Finely divided supported palladium particles are used as catalysts in many technical processes. Using MAPS we have recently investigated the interaction of hydrogen with the...

This proposal is part of our research programme to explore the experimental manifestation of topological properties of magnetic excitations. The honeycomb ferromagnet is...

Our neutron study using MARI/MERLIN on Ce(Ru1-xFex) 2Al10 reveals very interesting magnetic excitations and a manuscript is ready to submit to PRB. In x=0 (TN=27 K) a...

Via chi¿¿(Q,E) we aim to investigate the dependence of the Kondo temperature TK of YbInCu4 on external pressure and substitution. YbInCu4 undergoes a first-order isostructural...

We propose to use inelastic neutron scattering to search for the existence of spin fluctuations in two iron phosphide superconductors, (La,Ca)FePO and Sr2ScFePO3. The objective...

Type-I clathrates are of active interest for thermoelectric applications at temperatures above room temperature. This is mostly due to rattling modes of the guest atoms in these...

We propose to investigate the spin fluctuations in a candidate S=5/2 Kagome lattice. Previous neutron diffraction has found that RbFe2F6 maybe a good realization of a Kagome...

Organic ferroelectrics are important materials because of their technological applications in low-cost non-volatile memory elements. Single-crystal croconic acid (C5O5H2) is the...

Cerium-based Kondo lattice compounds have received great attention, owing mostly to the variety of exotic ground states that they exhibit (e.g., unconventional...

Among the all known crystalline ice phases, ice (Ih phase) exhibits anomalous thermal expansion behavior. We propose to measure phonon density of state of protonated ice (H2O)...

Ba4Mn3O10 and Sr4Mn3O10 crystallize in an orthorhombic crystal structure consisting of corrugated layers containing Mn3O12 polydedra. The magnetic susceptibility of the...

Recently it has been reported that YbAl3C3 undergoes an antiferromagnetic quadrupolar ordering transition at 80 K, Further study by Ochiai et al. revealed that the transition at...

This proposal requests 2 days on MERLIN to measure the INS spectrum of the novel perovskite type oxyhydride BaTiO3-xHx (x = 0.4). Prevision INS measurements, on TOSCA, have...

Polar or non-centrosymmetric ferri(-o)magnets offer a plethora of potential technological devices;the inherent magnetoelectric effect can underpin both pyroelectric or...

Ru4+ ions in Li2RuO3 are on a bipartite lattice and have an orbital degeneracy. The four electrons of the magnetic Ru4+ ions in the threefold-orbitally degenerate t2g manifold...

We have investigated the magnetic structure and crystal field excitations (CEF) of CeT2Al10 (T=Os and Ru). The observed magnetic moment along the c-axis does not agree with that...
