Abstract

Critical current densities of YBa₂(Cu_0.98M_0.02)₃O_y (M = Fe, Co, Ni) superconducting thin films made by laser ablation are investigated as a function of temperature and magnetic field. J_c in magnetic field shows that Ni-doping has a large effect on intragranular current while Fe-doping seems to have more influence on intergranular coupling. All three dopants give rise to basically same field-dependence of their volume pinning force F_p at elevated temperature (T = 60 K) except in the low field region (H < 2 T), and F_p can be scaled to a universal function F_p/F_p.max = b(1-b)². Hall effect measurements show that the effective carrier concentration is lower than that in undoped material.
