Neutron scattering studies of spin-phonon hybridization and superconducting spin gaps in the high-temperature superconductor La2−x(Sr,Ba)xCuO4
Abstract
We present time-of-flight neutron scattering measurements on single crystals of La2−xBaxCuO4 (LBCO) with 0≤x≤0.095 and La2−xSrxCuO4 (LSCO) with x=0.08 and 0.11. This range of dopings spans much of the phase diagram relevant to high-temperature cuprate superconductivity, ranging from insulating, three-dimensional commensurate long-range antiferromagnetic order, for x≤0.02, to two-dimensional (2D) incommensurate antiferromagnetism coexisting with …
