An enhanced magnetoresistance and a two-fold effect result from impurity dopant were observed in composites of La 0.67 Ca 0.33 MnO 3 /YSZ and La 0.67 Ca 0.33 MnO 3 /Fe 3 O 4 . Where YSZ represents yttria-stabilized zirconia and the doping level of both YSZ and Fe 3 O 4 is 1 mol%. Different electrica
A systematic investigation of lanthanum-based manganite, La 0.67 Ca 0.33 MnO 3 , has been undertaken with a view to understand the influence of varying crystallite size, in the nanoscale, on various physical properties. The materials were prepared by the sol-gel route by sintering at four different
