The magnetization of the PrFeAsO(0.60)F(0.12) polycrystalline sample has been measured as functions of temperature and magnetic field (H). The observed total magnetization is the sum of a superconducting irreversible magnetization and a paramagnetic magnetization. Analysis of dc susceptibility chi(T) in the normal state shows that the paramagnetic component of magnetization comes from the Pr(3+) magnetic moments. The intragrain critical current density (J(L)) derived from the magnetization data is large. The J(L)(H) curve displays a second peak which shifts towards the high-field region with decreasing temperature. In the low-field region, a plateau up to a field H(+) followed by a power law H(-5/8) behavior of J(L)(H) is the characteristic of the strong pinning. A vortex phase diagram for the present superconductor has been obtained from the magnetization and resistivity data. (C) 2011 Elsevier B.V. All rights reserved.
