The high-pressure form of solid water, ice III, is the equilibrium phase in contact with liquid water at pressures from about 2.0 - 3.5 kbar. Consequently, its properties are...

We propose to perform neutron diffraction experiments on powder samples of possible spin-induced multiferroic materials, 114CdMn7O12 and SrMn7O12, at ambient pressure and low...

Recently we studied L-alanine to 9.85 GPa. This is the highest pressure for which structural data are available for any organic system larger than methane. The results enabled...

Antiferromagnetic S = 1 one-dimensional chains exhibit a myriad of magnetic ground states depending on the balance between the spin exchange parameter and the single-ion...

The meta-orbital transition is a new theoretical concept to explain the nature of quantum criticality in heavy-fermion systems. Such a transition can occur e.g. as function of...

Clathrate hydrates (CHs) are ice structures in which water molecules (host) form cages through hydrogen bonds. The cages can accommodate various types of molecules (guests),...

We propose to perform neutron diffraction experiments under high-pressure on multiferroic TbMnO3 using WISH in combination with hybrid-anvil-type high-pressure device. Recently,...

Hertbertsmithite ZnCu3(OH)6Cl2 is a model S =1/2 kagome antiferromagnet, received much attention last years. From recent studies a sign of a nearby quantum phase transition...

The title compound, more succinctly referred to as HMT-hydrate, is a rare example of a water-framework zeolite structure with an organic guest molecule hydrogen bonded to the...

SiO2 is a prototypical network-forming glass that can be processed under high pressure and temperature conditions to give a permanently densified glass with a density that is up...

The AA'$3$Mn$_4$O${12}$ family of manganites with quadruple perovskite structure has recently attracted a lot of interest as a disorder-free model system for many of the...

We propose to perform neutron diffraction experiments on single crystals, 3R-AgFeO2 and 2H-AgFeO2 on WISH. Recently, we have studied magnetic orderings and ferroelectricity of...

A recent addition to the list of emergent materials is the ReBaCo4O7+delta family of compounds. Indeed, due to the magnitude of their oxygen uptake and release capability, they...

We propose to perform neutron diffraction experiments on a powder sample of the frustrated triangular lattice antiferromagnets α-NaFeO2 under high-pressure up to 18 kbar...

Complex mixed-ion pervoskites, ferroelectric material (1-x)Pb(Mg1/3Nb2/3)O3-xPbTiO3, attract plenty of applications due to high piezoelectric response. The difficulties result...

We propose to perform neutron diffraction experiments under high-pressure and high-magnetic-filed on multiferroic CuFeO2 using WISH in combination with hybrid-anvil-cell (up to...

In this proposal, we would like to propose to perform neutron diffraction experiments on the powder samples of the frustrated antiferromagnets AFeO2 (A=Cu and Ag) using WISH. In...

Ba3BiIr2O9 and Ba3BiRu2O9 undergo very unusual structural transitions at 74 and 176 K respectively, with instantaneous negative thermal expansion of up to 1% in the Ir compound....

Many novel electronic ground states form in close proximity to quantum critical points (QCPs), that is, the point where a continuous phase transition occurs at zero temperature....
