Neutron scattering study of soft phonons and diffuse scattering in insulating La$_{1.95}$Sr$_{0.05}$CuO$_{4}$

open access: yes, 2004
Soft phonons and diffuse scattering in insulating La$_{2-x}$Sr$_{x}$CuO$_4$ ($x=0.05$) have been studied by the neutron scattering technique. The X-point phonon softens from high temperature towards the structural transition temperature $T_{s}=410$ K ...
