摘要
本文运用群论方法,对高T_c Bi 系超导体中的Bi_2Sr_2CuO_(?)和Bi_2Sr_2CaCu_2O_8的晶格振动模进行了系统的对称性分类.给出了其布里渊区中(?)点,X 点和△线振动模式的对称分解和对称化基.
The symmetry classification of vibrating mode in Bi_2Sr_2CuO_6 and Bi_2Sr_2CaCu_2O_8 with high Tc are given systematically bystandard group theoretical methods.Their atomic displacements in normal vibrating modes in Brillouin Zone are listed for Γ,Xpoints and △ line.
