Composites with varying composition of ferromagnetic La0.7Sr0.3Mn0.96Co0.04O3, La0.7Sr0.3
MnO3 and ferroelectric BaTiO3 have been prepared using a solid-state ceramic method. The structure,
temperature dependence of DC resistivity, dielectric constant, magnetoresistance, and the hysteresis loops of
some samples have been investigated. Positive thermoresistive coefficient and colossal magnetoresistance
effects were observed in the samples consisting of 90mol% BaTiO3 and 97mol% La0.7Sr0.3MnO3. The
intermediate compositions (50mol% each other) are good candidates for application as multiferroic material.
