Paper Title:
Low Frequency Raman Modes of Bi2 −x PbxSr1.6Ln0.4CuO6 −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.
