Effect of granularity and annealing conditions on the magneto-resistance of the electron doped superconductor Nd{sub 1.85}Ce{sub 0.15}CuO{sub 4}
A single phase polycrystalline sample of Nd{sub 1.85}Ce{sub 0.15}CuO{sub 4} has been synthesized and well characterized. Detailed studies on electrical resistivity behavior of this system as a function of temperature and magnetic field reveal interesting features attributable to the granularity effects. These features have been qualitatively understood based on the interplay of Josephson junction coupling and quasi particle tunneling which dictates the evolution of the observed temperature and field dependent resistivity behavior of Nd{sub 1.85}Ce{sub 0.15}CuO{sub 4} system. The studies also reveal significant changes with respect to annealing conditions, indicating that such compounds are very sensitive to annealing conditions. It has been observed that prolonged annealing in Argon atmosphere leads to a decrease in normal state resistivity. This is associated with a decrease in the S-I-S type Josephson tunnel junctions perhaps due to improved inter-granular coupling, nevertheless they could not be completely eliminated.

Superconductivity in electron-doped PbBi 2 Te 4
Single crystals of In-doped PbBi 2 Te 4 are synthesized via a conventional solid-state method. Chemical analysis and Hall measurements indicate that In replaces Pb, introducing n-type carriers, creating Pb 1–x In x Bi 2 Te 4 . A superconducting transition is observed with a maximum transition temperature around 2.06 K for Pb 1–x In x Bi 2 Te 4 . Field-dependent transport measurements reveal type-II superconductivity and yield a maximum upper critical field around 1.55 T. Thermodynamic data indicates bulk superconductivity in the BCS weak-coupling limit. Finally, our findings establish an ambient-pressure superconducting system in the AM 2 X 4 family, and doped PbBi 2 Te 4 as a promising platform for the study of topological superconductivity.
