Vv. Petrykin et al., Structural disorder and degradation of superconductivity in the NdBa2Cu3Oz(z similar to 7) defects simulations, PHYSICA C, 357, 2001, pp. 388-392
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
