Abstract
In this study we present some results obtained from AC susceptibility (χAC) and transport measurements in polycrystalline samples of La0.7Ca0.3MnO3, in order to better investigate the relations between AC magnetic susceptibility and electrical transport measurements. In addition, it was also studied the inter- and intragranular characteristics of polycrystalline samples. Comparison among results obtained from χAC and transport measurements confirm that χ″ is an excellent tool to identify not only sample quality, but also to resolve between intra- and intergranular contributions. Besides that, experiments based on χAC are easier to prepare and perform than those based on the conventional transport measurments. In this context, it is appropriate to establish a link between transport and magnetic properties.
