Abstract

Abstract This short paper is an extension of our previous studies of low- T c stoichiometric NdBa 2Cu 3O z prepared by polymerizable complex method and via nitrates melting technique. The most recent results describing the effect of annealing 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 discovered by EXAFS.
