The quasi-kagome Kondo lattice CeRhSn exhibits intriguing properties, which ascribe to quantum criticality induced by geometrical frustration. Divergent Grüneisen ratios provide...

The iron-based superconductors (Fe-SC) are one of the most active and challenging topics in condensed matter physics. Very recently some of us (F. Bernardini et al.) have...

The Heisenberg antiferromagnet is a well-known model used to describe the magnetic properties of layered and metal-organic Mott insulators which have been explored both...

Bi1.7V8O16 is a member of the Hollandite family and its structure is base upon two sets of V4+ (S = 1/2) and V3+ (S = 1) chains. Bi1.7V8O16 undergoes a Metal-Insulator...

The magnetic ground state in geometrically frustrated lanthanide oxides is determined by the interplay between different magnetic interactions and crystal electric field (CEF)...

The frustrated magnetism of pyrochlores makes them candidates for applications in magnetic cooling and scientific instrumentation, and the proposal that they can be used to...

Thermal barrier materials are used in modern turbines to enable them to run above the melting temperature of the turbine blades. However, to go to higher temperatures (and...

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...

We propose to measure the powder-averaged spin excitation spectrum of LiFeAs, a new member of the ferropnictide family of superconductors. This compound is special because it is...

Recently we have synthesised new caged-type heavy fermion compounds CeT4Al15 (T=Rh and Ir) and investigated using bulk measurements. The low temperature susceptibility, heat...

We propose to use inelastic neutron scattering to search for the existence of spin fluctuations in two iron phosphide superconductors, LaFePO and Sr2ScFePO3. The objective is to...

NdMnO3 exhibits A-type antiferromagnetism with TN =73 K. At 15 K, Nd sublattice orders with a (0, -Fy, 0) type ferromagnetic arrangement. Mn spin reorientation from (Ax, Fy, 0)...

The triangular Heisenberg antiferromagnet is the classic example of the frustrated magnet, here the ground state forms a non-collinear 120° structure. A number of different...

We are proposing to use inelastic neutron scattering to map out the spin excitation in 100% detwinned SrFe2As2 single crystals. We want to sort out how the anisotropic magnetic...

Quantum spin liquids (QSL) are novel states of matter that display exotic ground states and fractionalized excitations. In two dimensions, the most promising model system is the...

Recentely we have measured (RB 1620263) pressure dependence of phonon modes in both the protonated (H2O) and deuterated ice (D2O) (Fig. 2) at ambient, 0.3 kbar, 1.0 kbar and 1.6...

We studied a new metamagnetic heavy-fermion (HF) compound YbRh3 Si7, synthesized for the first time. This is the first HF compound in the ScRh3Si7 family, for which the only...

FeNbSb-related compounds are a group of promising thermoelectric materials. Suppressing the lattice thermal conductivity through different phonon scattering mechanisms could...

Antimony sulfo-iodide (SbSI) exhibits strongly-coupled photoconductive, semiconducting, and ferroelectric properties. Until the discovery of the lead-oxide ferroelectric relaxor...

The reported structural phase transition in YMnO3 from P63cm to P63/mmc space group occurs at 1258 ±14 K. For low temperature phase (space group P63cm) the phonon modes are...
