用X射线旋进照相研究(Bi_(2-x)Pb_x)Sr_2CuO_y(0.1≤x≤0.6)晶体结构

In this paper, a structural study on series crystals of (Bi2-xPbx)Sr2CuOy (0.1≤ x ≤ 0.6) by X-ray precession method is reported. We found that in the lead substitution regions 0.4≤x≤0.5 this system is formed by two interpenetrating subsystems. One subsyst
