Effect of Yb Substitution in Bi_1.6Pb_0.4Sr₂Ca_2-xYb_xCu₃O_y Superconductor

Abstract:

This paper reports on the results of Yb substitution for Ca on the superconductivity and structural properties of Bi_1.6Pb_0.4Sr₂Ca_2-xYb_xCu₃O_y superconducting samples with x = 0.000, 0.025, 0.050, 0.100 and 0.200 which prepared by coprecipitation (COP) method. The samples were characterized by X-ray diffraction (XRD), field-emission scanning electron (FESEM), electrical and resistivity measurement by four-probe method. It was found that the substitution of Yb decreased the critical temperature (T_{c zero}), critical current density (J_c) and volume fraction of Bi-2223 phase. The samples have T_{c zero} in the range 77 to 100 K. T_{c zero} gradually decreased with an increase in Yb concentration, corresponding to small change of the carrier concentration. J_c was measured to be 5.7512 A/cm² for pure sample and decreased to 4.1910 A/cm² for x = 0.025 at 77 K. The crystallographic structure was found to change slightly from tetragonal to orthorhombic in Yb substituted samples. The lattice parameter c of Yb samples decreased due to the incorporation of Yb³⁺ (0.858 Å) with smaller ionic size compare to Ca²⁺ (0.99 Å). From the SEM observation, the grain connectivity became weak with smaller plate-like grain for x > 0.025 Yb concentration resulting in the decreased of J_c.
