Lattice dynamics of YCu2
Lattice dynamics of YCu2
The lattice dynamics of the orthorhombic YCu2 compound has been studied by inelastic neutron scattering on a single crystal. An axially symmetric Born-von Karman model was applied to fit the neutron data. Ab initio calculations of the lattice dynamics at the Gamma-point provided important additional...

The lattice dynamics of the orthorhombic YCu2 compound has been studied by inelastic neutron scattering on a single crystal. An axially symmetric Born-von Karman model was applied to fit the neutron data. Ab initio calculations of the lattice dynamics at the Gamma-point provided important additional information for the Born-von Karman fit procedure. The calculated phonon density of states was compared with time-of-flight experiments on powdered YCu2 sample material. The experimental studies were completed by Raman experiments and measurements of specific heat, thermal expansion, and compressibility. (C) 2002 Elsevier Science B.V. All rights reserved. |
