Internal friction study on CuFe2O4/PbZr0.53Ti0.47O3 composites

The xCuFe(2)O(4)(CFO)-(1-x)PbZr0.53Ti0.47O3(PZT) composites with x=0.1, 0.2, and 0.3 have been prepared by solid state reaction method. Two separate CFO and PZT phases without mixture phase have been confirmed by X-ray diffraction. The internal friction spectra at various frequencies were measured from 90 to 700 K. The internal friction peaks observed in those samples can be assigned to the contributions of ferroelectric and copper ferrite, respectively. There is no coupling of mechanical dissipation between the two components. The magnetoelectric (ME) property of the composites were also determined and the dependence of ME coefficient on CFO concentration were discussed. (C) 2004 American Institute of Physics.
