The magnetic excitations will be studied in a powdered sample of 3% CoO in 97% MgO in order to to study the excitations of isolated Co ions and of isolated pairs of Co ions....

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

La2O2M2OSe2 (M=Fe, Co, Mn) are layered Mott-insulating antiferromagnets with a potential to be a non-copper high-Tc superconductor. All compounds have shown unusual magnetic...

We have recently prepared mesoporous forms of various metals oxides. In some cases the imposition of a mesostructure changes other properties of the material significantly. One...

Geometrically frustrated spin systems are important owing to the fact that the geometry often suppresses conventional mean field ground states in favor of more unconventional...

This proposal aims to investigate the dynamics of the melting transition in H2O and CO2 when confined in a vycor (SiO2) matrix. The field of fluids in confined geometries is...

RMnAsO (R = Ce and La) are isostructural compounds with Fe-based oxypnictides, but has a unique properties as Mott insulator unlike the nonsuperconducting parent compounds of...

We propose to measure the magnetic excitations in malachite, a mineral that contains S=1/2 alternating chains with an alternation parameter of J'/J=0.5, just in the middle...

We aim to elucidate the low-energy electronic structure of two distinct dysprosium bisphthalocyanine single-molecule magnets by direct observation of crystal field excitations...

We propose to study the powder averaged spin fluctuations in a S=5/2 pryochlore - FeF3. Previous studies, corroborated by our own diffraction work on WISH, have measured that...

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

In strongly correlated electron systems, the proximity to magnetic ordering has been of special interest. Magnetism in this class of systems is often suppressed by the Kondo...

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...

Halogenomethane derivatives exhibit thermally induced solid¿solid phase transitions before melting that are attributed to the ability to gain rotational degrees of freedom in...

Heavy fermion compounds with a small energy gap opening in the strongly hybridised 4f-band at EF are currently under intensive investigations. Recently some of us have...

In the earlier research, the rheology of collapsing zeolites amorphized by temperature has been studied as well as the vibration that destabilize crystals. With the study of...
