Phonons and Lithium diffusion in LiAlO
Mayanak K. Gupta, Ranjan Mittal, Baltej Singh +5
We report on investigations of phonons and lithium diffusion in LiAlO based on inelastic neutron scattering (INS) measurements of the phonon density of states (DOS) in γ-LiAlO$…
Inelastic neutron scattering: A novel approach towards determination of equilibrium isotopic fractionation factors. Size effects on heat capacity and beta-factor of diamond
Andrey A. Shiryaev, Veniamin B. Polyakov, Stephane Rols +2
A new experimental method of determination of equilibrium isotopic properties of substances based on Inelastic Neutron Scattering (INS) is proposed. We present mathematical formali…
Spin-Phonon Coupling and Thermodynamic Behaviour in YCrO3 and LaCrO3: Inelastic Neutron Scattering and Lattice Dynamics
Mayanak K. Gupta, Ranjan Mittal, Sanjay K. Mishra +4
We report detailed temperature-dependent inelastic neutron scattering and ab-initio lattice dynamics investigation of magnetic perovskites YCrO3 and LaCrO3. The magnetic neutron sc…
Effect of Nd and Rh substitution on the spin dynamics of Kondo insulator CeFe2Al10
P. A. Alekseev, J. -M. Mignot, D. T. Adroja +7
The dynamic magnetic properties of the Kondo-insulator state in CeFe2Al10 (spin gap, resonance mode) have been investigated using polarized neutrons on a single crystal of pure CeF…
Phonons and Oxygen Diffusion in Bi2O3 and (Bi0.7Y0.3)2O3
Prabhatasree Goel, M. K. Gupta, R. Mittal +3
We report investigation of phonons and oxygen diffusion in Bi2O3 and (Bi0.7Y0.3)2O3. The phonon spectra have been measured in Bi2O3 at high temperatures up to 1083 K using inelasti…
