Raman scattering in La/sub 2-x/(Ba,Sr)/sub x/CuO/sub 4/ superconductors

Conference · · AIP Conf. Proc.; (United States)
OSTI ID:7127555
Raman scattering results at room temperature on powdered and solid samples of La/sub 2-x/(Ba,Sr)/sub x/CuO/sub 4/ in the range x = 0--0.2 are presented. Laser hetaing in air is shown to produce a surface layer of La/sub 2/O/sub 3/, a transparent insulator. The temperature dependence of the La/sub 2/O/sub 3/ Raman lines provides an indication of the temperature produced by the laser.
