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... -
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.... -
Magnetic structure of pyrochlore irridate Y2Ir2O7
We propose to study by powder neutron diffraction the ordered magnetic state of the pyrochlore compound Y2Ir2O7. There is currently an increasing interest in the condensed... -
Search for magnon-phonon coupling effect in metallic triangular antiferromagn...
Spin dynamics of non-collinear magnetic structures can exhibit the rare phenomena which go beyond the linear spin wave theory. Our previous studies on non-collinear... -
Determining the Induced Magnetism in Graphene by Polarised Neutron Reflectivity
This proposal aims to unambiguously understand the proximity effect between graphene and a transition metal using Polarised Neutron Reflectivity (PNR) measurements at the POLREF... -
Magnetic Ionic Liquids: measuring the ions diffusion as a function of the ap...
New ionic liquids made of diamagnetic cations and anions consisting of d- and f- transition metal complexes are gaining increasing recognition because of their marked... -
Investigations of some ruthenates with extended superexchange pathways
The superexchange interaction - in which the intervening oxygen mediates magnetism between two partially filled d shells- is well described by the semi-empirical... -
PNR of Magnetic Order in Delta-Doped Topological Insulators
We aim at studying proximity effects between a ferromagnetic thin film (either metallic or insulating) and a topological insulator (either undoped, or magnetically homogeneously... -
Paramagnetic excitations in NaFe0.53Cu0.47As
NaFe0.53Cu0.47As is an antiferromagnetic Mott insulator which connects unconventional superconductivity and Mott physics. The magnetic fluctuations in the ordered state has been... -
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... -
From giant magneto-elastic coupling to negative thermal expansion
We recently used high-resolution neutron diffraction on HRPD to observe the largest magneto-elastic coupling ever seen in a metallic magnet. The material studied was CoMnSi, a... -
Effect of oxygen vacancies on the phonon dispersion of pyrochlores
The frustrated magnetism of pyrochlores makes them candidates for applications in magnetic cooling and scientific instrumentation, and the proposal that they can be used to... -
