摘要：

The orthorhombic high-T//c Eu//1Ba//2Cu//3O//y crystals are investigated optically by the polarizing microscope. The crystals are optically anisotropic in the a-b plane, and the phase difference between the advanced- and the retarded-phase axis is 30 plus or minus 3 degrees along the a- and b-axes. According to the reflection formula for metals, the anisotropic conductivity between these two directions is analyzed. The anisotropy of a factor of about 2 is obtained.
