Synthesis and Microstructural Studies of Iron Oxypnictide LaO1-xFxFeAs Superconductors
Chandra Shekhar, Sonal Singh, P K Siwach +2
We report on the synthesis and structural/ microstructural studies of iron based fluorine doped LaOFeAs superconductors. We have successfully synthesized fluorine doped superconduc…
Low Field Magnetotransport in Manganites
P. K. Siwach, H. K. Singh, O. N. Srivastava
The perovskite manganites of general formula RE_1-xAe_xMnO_3 (RE= rare earth,AE=Ca, Sr, Ba and Pb)have drawn considerable attention, especially following the discovery of colossal…
Magneto-transport characteristics of La1.4Ca1.6Mn2O7 thin film deposited by spray pyrolysis
P. K. Siwach, H. K. Singh, O. N. Srivastava
Polycrystalline thin films of double layer manganite La_1.4Ca_1.6Mn_2O_7 (DLCMO) have been deposited by nebulized spray pyrolysis on single crystal LaAlO_3 substrates. These single…
Low field magneto-transport in La_0.7Ca_0.3MnO_3-PMMA composites synthesized by polymeric precursor route
Jitendra Kumar, Rajiv K. Singh, H. K. Singh +4
A detailed investigation of the effect of PMMA on the structure, microstructure and magneto-transport properties of manganite La_0.7Ca_0.3MnO_3 (LCMO) is presented. LCMO-PMMA nanos…
