Description:
Author(s): C. Stock, P. M. Gehring, H. Hiraka, I. Swainson, Guangyong Xu, Z.-G. Ye, H. Luo, J.-F. Li, and D. Viehland We use neutron inelastic scattering to characterize the acoustic phonons in the relaxor Pb(Mg 1/3 Nb 2/3 )O 3 (PMN) and demonstrate the presence of a highly anisotropic damping mechanism that is directly related to short-range polar correlations. For a large range of temperatures above T c ∼210 K, where d... [Phys. Rev. B 86, 104108] Published Tue Sep 18, 2012
