Raman-Studies of the Organic Superconductor
نویسنده
چکیده
The resonance Raman spectra of (IAuI)~-anions in the organic superconductor Y?-(BEDTTTF)2IAUI as well as in the electrolyte salt n-Bu4AuI2 are investigated. In contrast to /?-(BEDT-TTF)2I3 in the crystals of /?-(BEDT-TTF)2IAuI at low temperature only one Raman line at 120 cm" 1 corresponding to the symmetrical stretching mode of the (IAuI)"-anion is observed. No distinct change in the Raman spectra is observed at the superconducting transition.

Micro-Raman spectroscopy is recently advocated to be used for the identification of organic mediums of paintings although it is mainly used for identifying artists’ pigments. The current paper presents an effort for estimating the feasibility of micro-Raman spectroscopy for identifying Persian binding mediums used in historical paintings. To do so, samples were prepared in two main groups based...

XRD and Raman analyses were performed to probe the phase formation and the variation of the normal phonon frequencies of the high temperature superconductor GdBa2Cu3O7-δ upon Ce doping. It was found that in addition to the orthorhombic 123 phase, some nonsuperconducting peaks, which are mainly due to the BaCeO3 secondary phase, are also formed that suppress the superconducting transition tempe...
متن کاملPHONON SPECTRA OF HIGH TEMPERATURE SUPERCONDUCTOR Bi2Sr2Ca2Cu3O10 : THEORY AND EXPERIMENT*
Since the discovery of the high Tc superconductivity by Bednorz and Muller, several workers around the world have studied several systems to reach a really high Tc superconductor. As the strong electron-phonon coupling may be one of the possible origins of the high Tc, a knowledge about the phonon in these materials is essential. In order to investigate phonon spectra, Raman and infrared spectr...
