The magnetic field (B ) dependence of electric field versus transport current density (E-J characteristics) of Bi1.6Pb0.5Sr2-xHoxCa1.1Cu2.1O8+delta superconductor was studied for x from 0.000 to 0.200. The behavior of supercurrent flow under magnetic fields in Ho-doped (Bi,Pb)-2212 is explained using thermally activated flux-creep. The n -value and characteristic pinning energy ( Uc) estimated from E-J characteristics show that at applied fields, the flux-lines in Ho-doped samples are in the glass-state. A correlation is observed between n -index and Jc of doped samples. The highly enhanced critical current density (Jc) and n-index in both self- and applied-fields due to Ho-doping is of great scientific and technological significance.
