The rare-earth compound KYbSe2 provides a new chance for the study of frustrated magnets with strong SOC. It resembles YbMgGaO4 in many ways. Our susceptibility and specific... -
Assignment of higher-order transitions in the vibrational spectrum of the nov...
This proposal requests 2 days on MERLIN to measure the INS spectrum of the novel perovskite type oxyhydride BaTiO3-xHx (x = 0.4). Prevision INS measurements, on TOSCA, have... -
Magnetic excitations in La1.2Sr0.8NiO4 and LaSrNiO4
The recent exciting observations in the magnetic excitation spectra of cobalt oxides that are isostructural to the prototypical high-temperature superconducting cuprates have... -
Phonon Dispersion in the Organic Ferroelectric Croconic Acid
Organic ferroelectrics are important materials because of their technological applications in low-cost non-volatile memory elements. Single-crystal croconic acid (C5O5H2) is the... -
Spin gap opening associated with an extraordinary magnetovolume effect in som...
We have discovered an unusual magnetovolume effect in the 6H-perovskite oxides Ba3BiIr2O9 and Ba3BiRu2O9. These compounds contain isolated face-sharing bi-octahedral dimers... -
Vibrational dynamics and proton sites in proton conducting perovskites
Solid oxide fuel cells (SOFCs) operating at intermediate temperatures are a promising clean energy technology. At the heart of these devices is a proton conducting oxide... -

We propose to investigate the magnetic excitation spectra of tetravalent uranium ions in two isostructural, one-dimesional chains made up by aligned UM2 units, with M = Pt and... -
Investigation of the singlet ground states in PrT2Ga8 (T=Fe, Co) compounds
We are interested in investigating the nature of the ground states in the two titled compounds. Based on theoretical predictions, no magnetic ordering is expected in these... -
Magnetic excitations in the S=1/2 ferromagnetic semiconductor Lu2V2O7
Lu2V2O7 is a rare example of an S=1/2 pyrochlore. The fact that it is a ferromagnet with Tc=70 K belies the fact that it has some truly remarkable properties. These include the... -

Temperature dependence of phonon modes in protonated (H2O) and deuterated (D2...
Recentely we have measured (RB 1620263) pressure dependence of phonon modes in both the protonated (H2O) and deuterated ice (D2O) (Fig. 2) at ambient, 0.3 kbar, 1.0 kbar and 1.6... -
Inelastic neutron scattering and musr studies of the high-distorted double pe...
The heat capacity and neutron powder diffraction measurements of the double perovskites La2NaB′O6 (B = Ru5+, Os5+) with S=3/2 on the B¿ reveal an incommensurate magnetic... -
High energy spin excitations detwinned SrFe2As2 single crystals
We are proposing to use inelastic neutron scattering to map out the spin excitation in 100% detwinned SrFe2As2 single crystals. We want to sort out how the anisotropic magnetic... -
