Changes in the magnetic behavior of melt-textured Sm1.6Ba2.3Cu3.O-3(x) superconductor due to thermal neutron irradiation were investigated at 50 and 77 K. It was observed that J(c) was enhanced up to five times in magnitude after a irradiation fluency of 1.476 x 10(17) cm(-2). We discuss which types of pinning centers can be responsible for the observed behavior. (C) 2003 Elsevier Science B.V. All rights reserved.
