Dielectric properties of ceramics

This contribution presents an alternative synthesis route to produce highly resistive BiFeO3 multiferroic samples. The use of a fast sintering process followed by quenching to room temperature resulted in ceramic bulks with a resistance higher than 1012 Ohm.m at room temperature. In addition, anomalies found in the dielectric and resistivity characterization indicated the presence of magnetoelectric coupling in the synthesized BiFeO3 sample.
