Phonon density of states in La/sub 1.85/Sr/sub 0.15/CuO4
- 1. AT and T Bell Laboratories, Murray Hill, New Jersey 07974
Description
Specific-heat and inelastic neutron scattering studies of the high-T/sub c/ superconducting compound La/sub 1.85/Sr/sub 0.15/CuO4 are reported. A distinct anomaly of electronic origin in the specific heat is found at the superconducting transition temperature. The phonon density of states up to --20 meV is extracted from both experiments and the two sets of results agree well in yielding a sharply enhanced density of states at 10 meV, in accord with a recent theoretical study
