Abstract

sponsored_project_image

Magnetoelectric composites have sparked a lot of interest in order to produce high magnetoelectric coefficients in bulk and layered composites using different techniques. A wide range of magnetostrictive and piezoelectric phase combinations have been studied in the past, with lead (Pb) based materials being used as the piezoelectric component due to their strong piezoelectric response. However, many investigations focused on developing lead-free ferroelectric systems with electrical properties equal to those of lead-based systems due to environmental concerns.

The objective of this project is to achieve the requirements for a good magnetoelectric effect in a lead-free composite. In this study, phase structure, dielectric properties, magnetic properties and magnetodielectric have been investigated and analyzed the magnetoelectric coupling coefficient of the composites. In layered composites, we also discovered the self-biasing phenomenon, which allows considerable ME coupling in the absence of a DC magnetic field. The elimination of the necessity for DC magnetic bias in ME composites opens up a lot of opportunities for the development of components for a variety of applications. The ME coefficient is also greatly influenced by the thickness fractions of the two phases, thus we optimised the longitudinal and transverse ME response by altering the thickness of both BCZT and NZCF layers in the next work.

Output/Outcome of the Project

Output/Outcome of the project

In this project we have prepared laminated bi-layer and tri-layer magnetoelectric composites. We have used the lead free BZT-BCT layer as ferroelectric and & doped ZnFe2O4 as ferrite layer and observed appreciable values of magnetoelectric coefficient. We have developed self-biased magnetoelectric composites may be very useful for researchers working in this area. We have eight research papers in international journals of repute.

We have also developed two prototypes. Research fellow and PhD students in the project learnt a lot during the fabrication of prototypes, particularly electronics.

The instruments purchased in the project is also very helpful for other PhD students working in the similar area. Research scholars from Punjabi University, Patiala; Thapar Institute of Engineering and Technology, Patiala; Himachal Pradesh University, Shimla and Shoolini University, Solan are utilizing the instruments purchased in this project.
