Abstract
We performed X-ray diffraction and neutron scattering on a single crystal Lal.85Sr0.15CuO4. We found that the lattice anomaly is caused by the optical tilt phonon associated with the expansion of the c-lattice constartt below Tc. We also found that the (100) peak starts to develop below the HTT-LTO structural phase transition temperature. These results suggest that there is a strong relation between the superconductivity and the structural instability.
