dc.description.abstract	The magnetic field (B) dependence of electric field versus transport current density (E-J characteristics) of Bi(1.6)Pb(0.5)Sr(2-x)Ho(x)Ca(1.1)Cu(2.1)O(8+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 (U(c)) 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 J(c) of doped samples. The highly enhanced critical current density (J(c)) and n-index in both self- and applied-fields due to Ho-doping is of great scientific and technological significance.	en_US
