Raman Spectra of the New Series of Mercury Based High Tc Superconductor(Hg 0.8 Mo 0.2 )Sr 2(Y 1-x Ca x )Cu 2O 6+δ

Abstract The Raman spectra of the new series of mercury based high Tc superconductor (Hg 0.8 Mo 0.2 )Sr 2(Y 1-x Ca x )Cu 2O 6+δ are observed for the first time. The experimental results show that the typical phonon vibrational modes mainly appear at 145、320、440、578 and 592cm -1 . The intensities of the 145、320、440 and 578cm -1 peaks decrease with increasing Ca content x. In this article the phonon modes are assigned and their variation behavior with increasing Ca content x are discussed.
