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... -
Magnetic ground state of the candidate quantum ice material Pr2Sn2O7
Quantum spin ice is a novel form of matter in which the spins remain dynamic even at absolute zero due to quantum fluctuations. The requirements on the single-ion wavefunction... -
Phonon Anomalies in YMnO3 at High Temperature
The reported structural phase transition in YMnO3 from P63cm to P63/mmc space group occurs at 1258 ±14 K. For low temperature phase (space group P63cm) the phonon modes are... -
Quantum spin dynamics in molecular based triangular antiferromagnet Li2AMo3O8...
Recently new molecular based magnets Li2AMo3O8 (A = In and Sc), where Mo3O8 clusters form S = 1/2 triangular lattice Heisenberg antiferromagnet, were synthesized.... -
Ligand-field characterization and U-Pt bonding in uranium-based heterometalli...
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... -
Magnetic fluctuations in the presence of charge order RbFe2+Fe3+F6
We propose to investigate the magnetic fluctuations in a charge ordered magnet. Rb(Fe2+Fe3+)F6 is loosely based on a distorted Kagome framework with alternating chains of... -
Origin of Anomalous Thermal Expansion in Ih phase of Protonated (H2O) and Deu...
Among the all known crystalline ice phases, ice (Ih phase) exhibits anomalous thermal expansion behavior. We propose to measure phonon density of state of protonated ice (H2O)...
