    Notes: Abstract We investigated the anisotropic thermal conductivity in pyrolytic graphite by thermoreflectance. A laser-heated circular spot on a surface perpendicular to the planes developed into an elliptical temperature distribution which was recorded by a raster scanning technique at modulation frequencies ranging from 600 Hz to 100 kHz. The ratio of in-plane and perpendicular thermal conductivity was determined by fitting the phase of the temperature data with an analytical model, and was found to decrease with increasing modulation frequency. Highest conductivity values were considerably smaller than previously published data based on steady-state measurements. The frequency dependence and additional features in the phase profiles at high frequencies are discussed in view of sample surface preparation and the local nature of the thermoreflectance measurement.

    Micro-Raman scattering investigations on borocarbides (1996)
    Springer
    Journal of low temperature physics 105 (1996), S. 1629-1634 
    Details
    ISSN: 1573-7357

    Notes: Abstract Single crystalline specimens of RNi2B2C (R=Y, La) and Y(Ni.7Co.3)2B2C (non-superconducting reference) have been isolated from polycrystalline samples and successfully orientated. All four observable Raman peaks could be measured and unambiguously be attributed to vibrations of B and Ni atoms. Most important, we can show that a broadening of the B-A1g mode also occurs in non-superconducting reference samples and should therefore not be taken as an evidence for a dominant role of the B-A1g mode in the pairing interaction.
