Neutron scattering study of soft phonons and diffuse scattering in insulating La${}_{1.95}$Sr${}_{0.05}$CuO${}_4$

Shuichi Wakimoto, Seunghun Lee, Peter M. Gehring +2

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 t…
