Magnetic Excitations of Isolated and Pairs of Co Ions and in MgO
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.... -
Magnetic excitations in mesoporous hematite
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... -
Crystal Field Splitting in Dysprosium Double Decker Single Molecule Magnets
We aim to elucidate the low-energy electronic structure of two distinct dysprosium bisphthalocyanine single-molecule magnets by direct observation of crystal field excitations... -
The dynamics of the calcium-ammonia-graphite decomposition with hydrogen
Graphite intercalation compounds (GICs) have potential as hydrogen storage materials, from direct physisorption of H2 or as a high surface area nanostructured host for metal... -
INS on a 2D quantum spin liquid candidate material without structural disorder.
The ordered double perovskite Sr2CuWO6 is a quasi-two dimensional J1/J2 frustrated square lattice model antiferromagnet. The divalent Cu carries S = 1/2 while the W (VI) is 4d0.... -
Determination of the crystal-electric field in geometrically frustrated pyroc...
Geometrically frustrated systems such as pyrochlore compounds receive much attention since they display exotic magnetic states. The explanation lies on the large degeneracy of... -
Neutron scattering and muSR studies of magnetic phenomena in YFe2Al10: case s...
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... -
EuCu2(Ge1-xSix)2 : from mixed valence to stable moment excitation spectrum
An inelastic neutron scattering experiment is proposed to study magnetic excitation spectra of representative EuCu2(Ge1-xSix)2 samples. These sytems provide the possibility to... -
Investigation of the temperature dependence of Q-dependent vibrational modes ...
This proposal seeks to measure the poly-CINS (polycrystalline coherent inelastic neutron scattering) spectrum from magnesium deuteride (MgD2); a powder sample on the MARI... -
Study of the protein denaturation in glassy matrices
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... -
Vibrational density of States and Occupational Disorder in the Halogenomethanes
Halogenomethane derivatives exhibit thermally induced solid¿solid phase transitions before melting that are attributed to the ability to gain rotational degrees of freedom in... -
Spin-orbit coupling and spin dynamics in hexagonal iridate
Hexagonal iridate Na2IrO3 has recently been proposed as a candidate material to exhibit strong spin-orbit coupling effects which may stabilize a Mott insulating state with... -
Structural study of the higher oxidation states of the nickel positive electrode
Although the first patents involving the nickel positive electrode are more than 100 years old, our understanding of the phases involved in this system is still not complete. As...
