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
