Investigations on Magnetoelectric Composites Based on Terfenol-D & PZT in an Alternating Magnetic Field Conditions

In this paper a study on the magnetostrictive-piezoelectric composite material with different configuration in a variety of external magnetic field changes was presented. An experimental setup for investigation of properties of magnetostrictive-piezoelectric materials was prepared. The hybrid structure was made of magnetostrictive composite (based on Terfenol-D) and piezoelectric materials. Experimental results shown the response of prepared hybrid material to the rate of magnetic field changes at the same direction of magnetic field vector. Based on the obtained results, it was found that the prepared composite material exhibits magneto-electric effect in the case of work in a variable magnetic field. This phenomenon could be used as a support for the tensiometers during measurements of deformation or cracks propagation of the samples during fatigue tests.
