Magneto-transport behaviour of Bi2Se3-xTex: Role of disorder
E. P. Amaladass, T. R. Devidas, Shilpam Sharma +3
Magnetoresistance and Hall resistance measurements have been carried out in fastcooled single crystals of Bi2Se3-xTex (x: 0 to 2) in 4 to 300 K temperature range, under magnetic fi…
Evidence of diamagnetic fluctuations above Tc in BaFe2-xCoxAs2 single crystals
Biplab Bag, K. Vinod, A. Bharathi +1
Increasing doping concentration (x) in Pnictide superconductors results in the suppression of long range magnetic order and the emergence of superconductivity. While doping destroy…
