Incommensurate-commensurate phase transitions in K2SeO4
Materials with incommensurate structures often show exotic properties (such as charge density waves). The development of reliable and efficient refinement techniques for such... -
High energy spin excitation in superconducting Rb0.8Fe1.68Se2
Superconductivity (SC) in unconventional superconductors is believed to be related to magnetism. However, in AyFe1.6+xSe2 (A = K, Rb, Cs) system discovered in late 2010, the SC... -
The use of lipid sponge-like nanoparticles as carriers for macromolecules and...
Conventional ways to administer and deliver drugs have reached its limitations. These methods can be still used for small and simple molecules. However, new carriers have to be... -
Inelastic Spectroscopy of the Mobile Phase of Ammonia Borane
Ammonia borane (AB) is one of the most promising hydrogen storage materials. There has recently been work on a more mobile phase of AB (denoted AB*) which is formed (via the... -
Spin excitations in the paramagnetic phase of a charge-ordered bilayered mang...
In a previous experiment we measured the spin wave spectrum of the half-doped bilayer manganite Pr(Ca,Sr)2Mn2O7 in its spin, charge and orbital ordered phase. The data, which... -
Spin wave in Nd2CuO4-- Determination of the magnetic exchange couplings of th...
Since the discovery of high transition temperature (high Tc) copper oxide, many efforts have been made on the understanding of its electronic and magnetic properties. Although... -
Hourglass dispersion in overdoped manganites
Overdoped manganites were recently shown to exhibit stripe-like ordering of charges orbitals and magnetic moments. The magnetic excitations in these materials show close... -
The magnetic excitation spectrum in Fe1.07Te
We propose to investigate the high energy magnetic spectrum in Fe1.07Te. We have previously investigated the fluctuations in Fe1.14Te in the incommensurate phase and have found...
