Abstract / Description:A neutron-scattering study of nonsuperconducting La2-
xSrxCaCu2O6 (x=0 and 0.2), a bilayer copper oxide without CuO
chains, has revealed an unexpected tetragonal-to-orthorhombic
transition with a doping dependent transition temperature. The
predominant structural modification below the transition is an
in-plane shift of the apical oxygen. In the doped sample, the
orthorhombic superstructure is strongly disordered, and a
glassy state involving both magnetic and structural degrees of
freedom develops at low temperature. The spin correlations are
commensurate.
