| Abstract: | The (1−x) Ni0.92Co0.03Mn0.05Fe2O4 + (x) BaTiO3 magnetoelectric (ME) composite have been prepared using conventional double sintering ceramic process where x varies as 1.00,
0.85, 0.70, 0.55 and 0.00. The presence of both phases has been confirmed by X-ray diffraction and the microstructure study
will be carried out by SEM technique. The dc resistivity and thermo-emf of the samples have been studied with variation in
temperature. The variation of dielectric constant (έ) and loss tangent (tan δ) will be measured in the frequency range 100 Hz–1 MHz.
The ac conductivity has been derived from dielectric constant (έ) and loss tangent (tan δ). The static value of magnetoelectric
conversion factor dc (ME)H has been studied as a function of intensity of magnetic field. |
