It has recently been discovered than the rutile phase of zinc fluoride shows negative thermal expansion along all three crystallographic axes. What is highly unusual about this...

The vast majority of known ferroelectrics are inorganic compounds such as barium titanate and potassium dihydrogen phosphate. Contrary to naïve expectation, ferroelectricity in...

Polaron-mediated colossal magneto-resistance (CMR) was predicted decades ago but never been experimentally established unambigously, despite the 'universal' existence of...

KFe0.8Ag1.2Te2 is made of 2x2 squares of Fe atoms, upon lowering temperature the system spontaneously undergoes a transition that breaks the fourfold rotational symmetry. A...

In the earlier studies, so far, condensed matter physicists and materials scientists have mainly explored the interesting physical properties of Ir-based double perovskites...

We want to elucidate whether the so-called ¿strong-fragile¿ transition reported for water mixtures is a universal phenomenon driven by confinement effects originated by the...

Understanding the structures of complex materials is key understanding their properties. Here we wish to determine the structure, both atomic and magnetic, of a complex...

This proposal is to observe single-spin diffusive motion on a two-dimensional (2D) percolating network having a fractal geometry. The random walker¿s travel times on a...

The organic-inorganic perovskites (CH3NH3Pb(Br,Cl,I)3) have been identified as efficient photovoltaic materials. Theoretical calculations have suggested that the low energy...

We propose to carry out inelastic neutron scattering experiments to study magnetic excitation spectrum in FeCrAs. FeCrAs exhibits magnetic ordering around 125 K, which is...

The physisorptive capacity of graphite-based nanomaterials for hydrogen is strongly dependent on their internal surface areas and pore dimensions. We have made electrospun...

KMnF3 perovskite undergoes 3 structural, and two magnetic phase transitions on cooling from 300 K to 2 K. Above 185 K the compound is in the aristotype structure, on cooling...

We have discovered a novel type of quantum spin liquid in a hexagonal lattice of Ru5+ dimers in Ba3ZnRu2O9, where any traces of the Curie tail or glassy behavior have not been...

We request 4 days on IRIS to investigate the diffusional and rotational dynamics of the alkalide forming, fully methylated aza-crown hexamethyl-hexacyclen (HMHC) in...

New perovskite phases containing lead and halogens with a molecular cation are providing new options for materials in solar cells, giving unusually high efficiencies in...

The AFM ground state of CeCu2Ge2 can be continuously suppressed by Co doping and NFL type behavior is seen around the critical concentration xc = 0.6. The electrical resistivity...

The aim of this proposal is to determine the crystal structure of Fe3O4 (magnetite) in its low temperature phase below the Verwey transition. Despite a considerable amount of...

Magnetic frustration - the inability to mutually satisfy all magnetic interactions in a system - is the source of many interesting phenomena, including spin liquids and ices. In...

Ammonia borane (AB) is one of the most promising hydrogen storage materials. We have extensively studied the low temperature behaviour of this material This proposal asks for 3...

Quantum phase transitions, where correlation length and time scales diverge, are of broad interest to the condensed matter physics community. The new layered material YFe2Al10...
