Superstructure in nano-crystalline Al50Cu28Fe22 alloy
T. P. Yadav, N. K. Mukhopadhyay, R. S. Tiwari +1
This work reports the formation of nano- crystalline Al50Cu28Fe22 by high-energy milling. For obtaining the nano-crystalline material, the Al50Cu28Fe22 alloy synthesized through sl…
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…
Nucleation and growth of catalyst-free ZnO nanostructures
Jai Singh, Anchal Srivastava, R. S. Tiwari +1
This paper deals with the investigations on the nucleation and growth of ZnO nanostructures in a catalyst free synthesis. The ZnO nanostructures have been formed by evaporation of…
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…
