Polycrystalline pyrochlore Lu2Ti2O7 pellets are irradiated with 600-keV Kr^3+ions up to a fluence of 1.45 ×10^16Kr^3+/cm^2. Irradiation induced structural modifications are examined by using grazing incidence x-ray...
Barium molybdate(Ba Mo O4) micro- and nano-crystals were synthesized by the coprecipitation method. Utilizing the water as the solvent provides octahedron-like nanostructures. These nano-crystals were structurally c...
We present a study of their structure, morphology, electrical and magnetic properties on the (Ca1–xSrx) RuO3 system for x = 0.0, 0.07, 0.10, 0.15 and 1.0. The samples were prepared by the solidstate reaction method i...
