In order to explore the possibility of tuning superconducting and ferromagnetic transitions by Cu doping (for Ru) in GdSr2RuCu2O8, we have carried out synthesis and characterization of GdSr2Ru{1-x}Cu{2+x)O8 (x = 0, 0.05, 0.1, 0.2) and studied their p

A series of quaternary intermetallics having the nominal composition Sm(1)Ru( n )B( n )C(1), (designated as 1nn1 compounds, n =1, 2, 3 and 4), have been prepared by arc melting route. X-ray diffraction patterns reveal two types of compounds in the ca

In an earlier paper [G. Ghosh, V.S. Sastry, C.S. Sundar, T.S. Radhakrishnan, Solid State Commun. 105 (1998) 247] we have reported that at low temperatures the ideal hcp ( c / a ∼1.63) solid C 70 transforms to a monoclinic structure, in a single ste
