Critical properties in single crystals ofPr1−xPbxMnO3

OPTICAL PROPERTIES OF CdIn2S4 SINGLE CRYSTALS

-The optical absorption of CdIn2S4 single crystals has been measured at several temperatures in the spectral range from 0.4 to 0.8 p. The interband gap for the indirect allowed transition was found to have a temperature coefficient of 9.5 X 10J eV/deg between 100 K and 300 K and to have a value of 2.7 eV when extrapolated to 0 K. From a temperature dependence of the photocurrent corresponding t...

Magnetic Properties of Lu2Co17-xSix Single Crystals

Abstract. Magnetic properties of Lu2Co17-xSix single crystals grown by the Czochralski method were investigated. The homogeneity range of Si substitution for Co extends up to x = 3.4. The unit cell volume, V, Curie temperature, TC, and spontaneous magnetic moment, Ms, decrease monotonously with increasing Si content. Upon Si substitution, the spin-reorientation transition occurring in Lu2Co17 a...

Physical properties of SrSn(4) single crystals.

We present detailed thermodynamic and transport measurements on single crystals of the recently discovered binary intermetallic superconductor, SrSn(4). We find this material to be a slightly anisotropic three-dimensional, strongly coupled, possibly multiband, superconductor. Hydrostatic pressure causes a decrease in the superconducting transition temperature at the rate of ≈ - 0.068 K kbar(-1)...

Dielectric properties of lithium triborate single crystals

Phonon properties of CoSb2 single crystals.

The phonon properties of CoSb(2) have been investigated by Raman scattering spectroscopy and lattice dynamics calculations. Sixteen out of eighteen Raman active modes predicted by factor-group analysis are experimentally observed and assigned. The calculated and measured phonon energies at the Γ point are in very good agreement. The temperature dependence of the A(g) symmetry modes is well repr...
