Abstract? Multiferroics and ferroics of composition x a0,8Pb0,2TiO3/(1-x)Cu0,3Ni0,1Zn0,6Fe2O4 were prepared by the ramic method. Powders and pellets were sintered at 1100°C r 2 h. No structural changes were observed in composite aterials, therefore both phases retain their structure after ntering. The effect of compositional variation on structural electric and magnetic properties was investigated and lated to the attenuation properties. The increase of the rroelectric phase changes the magnetic and dielectric havior in the explored frequency region (from 1 MHz to 1.8 Hz). Results allow us to infer that composites with higher an 50% w/w of ferrite mass, could be considered as an tenuator material of electromagnetic energy in the explored equency range.
