　View Summary

The charge-density-wave (CDW) phase transition in (Formula presented) is studied by femtosecond time-resolved reflection. We observed coherent optical phonons in the reflectivity signal in both the normal and the CDW states. Below the transition temperature (Formula presented) six vibrational modes were clearly detected. Four of them, centered at 64, 78, 85, and (Formula presented) were enhanced below (Formula presented) We conclude that the generation of these coherent phonon modes are closely related to the CDW state. © 1998 The American Physical Society.

　View Summary

Local structure of infinite layered superconductor Sr&lt;SUB&gt;1&lt;/SUB&gt;-xLa&lt;SUB&gt;x&lt;/SUB&gt;CuO&lt;SUB&gt;2&lt;/SUB&gt; in low temperature was investigated by EXAFS, X-ray diffraction and Raman spectroscopy. EXAFS showed that the Cu-O bond distance slightly expanded in a range &lt;0.1&amp;Aring; with lowering temperature down to 20K.&lt;BR&gt;The expansion was remarkable below Tc(onset)=43K. Tetragonal lattice parameters shrank with lowering temperature but the shrinkage of a-parameter seemed to be almost saturated below Tc(onset). Oxygen atoms may slightly shift their positions above and below the CuO&lt;SUB&gt;2&lt;/SUB&gt; plane. Raman spectrum of Sr&lt;SUB&gt;1&lt;/SUB&gt;-xLa&lt;SUB&gt;x&lt;/SUB&gt;CuO&lt;SUB&gt;2&lt;/SUB&gt; superconductors were Raman active although infinite layered structure should be Raman inactive from its symmetry. Resonance Raman peaks were observed at 151cm&lt;SUB&gt;-1&lt;/SUB&gt; and 304cm&lt;SUB&gt;-1&lt;/SUB&gt; in a usage of 4880&amp;Aring; Ar ion laser. Its energy of 2.54eV almost corresponds to that of the exitation between lower and upper Hubard bands. The peak intensities increased with lowering temperature even above Tc(onset). The intensity change may also be related to the change observed with both X-ray absorption and diffraction in local structure with temperature. The CuO&lt;SUB&gt;2&lt;/SUB&gt; plane may buckle as reported in atomic pair distribution function refinement of neutron diffraction data on (Nd.Ce)&lt;SUB&gt;2&lt;/SUB&gt;CuO&lt;SUB&gt;4&lt;/SUB&gt; in low temperature.
