Abstract
This short paper is an extension of our previous studies of low-T-c stoichi ometric NdBa2Cu3O2 prepared by polymerizable complex method and via nitrate s melting technique. The most recent results describing the effect of annea ling time and temperature on the superconducting transition for the samples prepared from the fine precursor are presented. The defects simulation was applied to understand the previously unexplained structural data discovere d by EXAFS. (C) 2001 Elsevier Science B.V. All rights reserved.
