Study of vibron quasibound state in RAg1-xCuxAl3, 0<x<1 (R=Ce and La) through...
We propouse the study of crystal-field or vibron excitations along the series RAgxCu1-xAl3 (R=Ce and La, 0<x<1), where we expect to studing two main aspects. The first one... -
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... -
Search for magnetic correlations in Fe phosphide superconductors
We propose to use inelastic neutron scattering to search for the existence of spin fluctuations in two iron phosphide superconductors, (La,Ca)FePO and Sr2ScFePO3. The objective... -
Melting point dynamics of Confined fluids
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... -
Inelastic neutron scattering study on CeMnAsO and LaMnAsO
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... -
Giant magneto-elastic interactions and changes in the phonon spectrum of CoMnSi
Neutrons are almost never used to examine the role of phonons in materials with large magnetocaloric effects, despite the large magneto-elastic coupling often exhibited by them.... -
Study of hybridization gap and insulator-metal transition in caged compounds ...
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... -
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...
