The magnetoelectric (ME) properties of PbZr0.65Ti0.35O3-BaFe12O19 (PZT-BaM) multiferroic ceramic composites have been investigated in this work. These materials, containing both the ferroelectric PZT and ferrimagnetic BaM phases, were prepared from the conventional solid-state reaction method, and their main (micro) structural characteristics are provided. The ME measurements were performed over wide frequency and temperature ranges, and the influence of the BaM content was appraised. An enhanced ME coefficient (alpha) was obtained for the applied magnetic field of 0.8 kOe, at 97 kHz. In addition, the results reveal a high thermal stability of alpha in the whole analyzed temperature range, showing that the studied PZT-based ceramic composites have great potential for practical applications.
