摘要：

Raman spectra of Y1-xCaxBa2Cu4O8 were investigated. At the Ca concentration of 10 %, which was solubility limit, frequency shift of 2 cm-1 was observed in the peaks at 492 cm-1 and 595 cm-1 assigned to the motion of O(1) and O(4) atoms, respectively. It is suggested that the stractural change due to the Ca substitution is too small to change the frequency of the Raman peaks.
