Lattice Dynamics of the Force Constant Disordered Crystal Pd0.90Ru0.10

Abstract: o single crystal a t room temperature are measured along the directions [loo], [110], and [ l l l ] by inelastic neutron scattering. The Born-von Karman analysis, using the seven-neighbour model, is carried out, and the force constants and elastic constants are calculated. The phonon frequency shifts, Ao(q), and the self-energy functions, Cj(q, w , ( q ) ) , for all the branches are determined from the experimental phonon data for Pd,,,,Ru,,,, and Pd. The self-energy shows a rich and coherent structure and rev… Show more
