Comparison of the superconducting critical transition temperature of LaBaCaCu3O7-d and NdBaCaCu3O7-d
V. P. S. Awana, M. A. Ansari, Rashmi Nigam +3
LaBaCaCu3O7 (La:1113) and NdBaCaCu3O7 (Nd:1113) compounds are synthesized by solid state reaction route. Both compounds crystallize in tetragonal structure. Four probe resistivity…

Effect of Sr substitution on the stability of CuO chains in oxygen and nitrogen annealed YBa2-xSrxCu3O(x = 0.0, 0.50, 1.0) superconducting system
M. A. Ansari, V. P. S. Awana, Anurag Gupta +2
Samples of YBa2-xSrxCu3O7-d (x = 0.0, 0.50, 1.0) series were synthesized by solid-state reaction and first annealed in flowing O2 gas. All samples crystallized in orthorhombic stru…
