Of all multiferroic materials, BiFeO3 stands out particularly with its both magnetic and ferroelectric transition temperatures above room temperatures, more interestingly having...

In Ce-based heavy fermion materials, there is competition between the interactions which lead to a magnetically ordered arrangement of the Ce magnetic moments, and the...

R2RuO5 (R = Pr, Nd, Sm, Gd, Tb) are known to exhibit interesting physical properties. They all show magnetic ordering between 8 ¿ 24 K. They also show large Sommerfeld...

Cadmium cyanide is a negative thermal expansion material: it shrinks – rather than expands – when heated. We are proposing to carry out an inelastic neutron scattering...

The heat capacity and neutron powder diffraction measurements of the double perovskites La2NaB′O6 (B = Ru5+, Os5+) with S=3/2 on the B¿ reveal an incommensurate 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...

The proposed experiment is addressed to use the MARI spectrometer to study the thermal denaturation process of the psychrophile enzyme alpha-amylase in presence of bioprotectant...

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...

Ba2CuTeO6 is a recently discovered S=1/2 spin ladder system containing Cu2+ ladders. Our experiments indicate that it is extremely close to the theoretically predicted quantum...

Chromium is unique amongst the d-band elemental metals in that it has a spin density wave ground state. The spin density wave is caused by Fermi surface nesting between electron...

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...

An understanding of the electronic structure of the actinide elements is one of the most intriguing and complex topics in contemporary chemistry. In particular the magnetic...

The recent discovery of the iron arsenide family of layered superconductors RFeAsO1-xFx and AFe2As2 with transition temperature up to 52K has generated tremendous interest as...

Recently new molecular based magnets Li2AMo3O8 (A = In and Sc), where Mo3O8 clusters form S = 1/2 triangular lattice Heisenberg antiferromagnet, were synthesized....

NaYbS2 is yet unexplored material which crystallizes in the delafossite structure with general formula ABX2. The magnetic ions Yb3+ form perfect triangular layers separated by...

The non conventional d-wave superconductivity in Heavy Fermion compounds seems to be triggered by spin fluctuations, which is in strong contrast to conventional...

A new material, Ba2LuMoO6, has been proposed to be an example of a valence bond glass. It bears numerous similarities in bulk measurements to Ba2YMoO6, which was the first...

We propose to investigate the magnetic excitation spectra of tetravalent uranium ions in two isostructural, one-dimesional chains made up by aligned UM2 units, with M = Pt and...

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

Isostructural Sr2CuBO6, B=W or Te, exhibit different magnetic structures k=[0 1/2 1/2] vs [1/2 1/2 0], leading to the suggestion of a reversal in the ratios of the nearest and...
