Phase formation and superconductivity of Fe-tube encapsulated and vacuum annealed MgB2
K. P. Singh, V. P. S. Awana, Md. Shahabuddin +7
We report optimization of the synthesis parameters viz. heating temperature (TH), and hold time (thold) for vacuum (10-5 torr) annealed and LN2 (liquid nitrogen) quenched MgB2 comp…
Impact of Zn substitution on phase formation and superconductivity of Bi1.6Pb0.4 Sr2Ca2Cu3-xZnxO10 with x = 0.0, 0.015, 0.03, 0.06, 0.09 and 0.12
R. B. Saxena, Rajiv Giri, V. P. S. Awana +8
Samples of series Bi1.6Pb0.4Sr2Ca2Cu3-xZnxO10 with x = 0.0, 0.015, 0.03, 0.06, 0.09 and 0.12 are synthesized by solid-state reaction route. All the samples crystallize in tetragona…
Revival of Superconductivity by Y3+/Ca2+ substitution in YBa2Cu2.7Co0.3O7 without reported phase transformation
M. A. Ansari, Rashmi Nigam, V. P. S. Awana +7
Results of phase formation, resistivity (r), and thermo-electric power (S), are reported on Y1-xCaxBa2Cu2.7Co0.3O7 compounds with x = 0.1 and 0.2. Pristine compound i.e. without Co…
