Dielectric and magnetic properties of BaTiO3-NiFe2O4 multiferroic composites
(Elsevier Sci Ltd, Oxford, 2014)
Multiferroic composites with the general formula x BaTiO3-(1-x) NiFe2O4 (x=0.5, 0.7, 0.8) were prepared by mixing chemically obtained nickel ferrite and barium titanate powders. Optimum processing parameters for a reduction ...
Structural and electrical properties of sintered Fe2O3/TiO2 nanopowder mixtures
(Elsevier Sci Ltd, Oxford, 2014)
Starting nanopowders of TiO2 (anatase 99.7%) and alpha-Fe2O3 (hematite) were mixed in the weight ratios 60:40 and 40:60. Green samples were sintered in the temperature range 750-1250 degrees C in air. Structural, morphological ...
