Conversion of electric energy to magnetic field (or vice versa) plays an important role in many devices such as sensors, transducers, etc. One way in principle to accomplish this is the production of magneto-electric (ME) ceramic composites. These composites contain ferroelectric and ferromagnetic phases. Under the applied magnetic field, due to its magnetostrictive nature, dimensional changes occur in the ferromagnetic component. These changes result in induced electrical field due to piezoelectric effect in ferroelectric component. The aim of the project is the production and characterization of magneto-electric ceramic composites and maximization of certain properties by using Sr, Mn, Bi doped PZT as the ferroelectric phase and Cu, Co, Mn doped Nickel-Ferrite as the ferromagnetic phase.
