| Zusammenfassung: | The standard double sintering ceramic method was used to prepare the magnetoelectric (ME) composites with ferrite and ferroelectric phases. The crystalline phases of the sintered samples were studied by the X-ray diffraction technique. The dielectric parameter such as dielectric constant was determined as a function of frequency (in the range 100Hz-1MHz) and temperature (room temperature to 650 deg C) at different test frequencies. The DC resistivity as a function of temperature and AC conductivity as a function of frequency were studied for different compositions. Effect of resistivity on ME voltage coefficient is explained. |
