Low Frequency Raman Modes of Bi_{2 −x}Pb_xSr_1.6Ln_0.4CuO₆ _−δ

Abstract:

Raman measurements were made on polycrystalline Bi2􀀀xPbxSr1:6Ln0:4CuO6􀀀 for Ln=fLa,Nd, Sm, Eug with various x and doping states. Our measurements suggest a signi cant Bicontribution to the 118cm􀀀1 mode but not to the 70cm􀀀1 mode which instead shifts to lowerfrequencies with increasing number of CuO2 layers in the Bi-based family. Shifts in the O(2)Srapical oxygen mode can be attributed to unit cell contraction within experimental error.
