Raman scattering investigation of a single-crystal-like YBa2Cu3O7-y film.

Presents information on a study which compared room temperature Raman spectra from a single-crystal-like film of YBa[sub2]Cu[sub3]O[sub7-y] fabricated by pulsed laser deposition, with similar spectra of a single crystal of YBa[sub2]Cu[sub3]O[sub7-y]. Description of the single crystals obtained as free-growing platelets from nonstoichiometric partial melts; Demonstration of the micro-Raman technique; Fabrication of the film used in the experiments.
