In the present work, polycrystalline samples with compositions MgB₂ + 3wt% GO + x wt% C₆H₈O₇ (x = 0, 5 and 10) have been synthesized to study the effect of combined addition of graphene oxide (GO) and citric acid (C₆H₈O₇) on superconducting properties of MgB₂. X-ray diffraction studies show the formation of hexagonal crystal structure of MgB₂ with space...

In the present paper we report the effect of graphene oxide (GO) doping on the structural and superconducting properties of MgB₂. Bulk polycrystalline samples have been synthesized via a solid state reaction route with compositions MgB₂ + x wt% of GO (x = 0, 1, 2, 3, 5, 7 and 10) by sintering at ~850 ° C in a reducing atmosphere of Ar/H₂ (9:1). The x-ray diffraction...

In the present paper, DC magnetization investigation on the insulating nanocrystalline powder samples of Ti1−xMnxO₂ (x = 0, 0.05, 0.10, and 0.15) prepared by simple chemical route is reported. Structural measurements revealed phase pure anatase structure of TiO₂ when x ≤ 0.05 and a mixture of anatase and rutile TiO₂ along with the...
