Study Of Multiferroic Properties Of Ferroelectric- Ferromagnetic Heterostructures Bzt-Bct/Lsmo, Md Abdullah-Al Mamun

MSU Graduate Theses

Currently, there has been a flurry of research focused on multiferroic materials due to their potential applications. Lead (Pb)-based ferroelectric and multiferroic materials (PZT, PMN-PT, PZN-PT etc.) have been widely used for sensors, actuators, and electro-mechanical applications due to their excellent dielectric and piezoelectric properties. However, these materials are facing global restriction due to the toxicity of Pb. In this thesis, multiferroic properties of ferroelectric-ferromagnetic heterostructures consist of Pb-free perovskite oxides 0.5Ba(Zr_0.2Ti_0.8)O₃-0.5 (Ba_0.7 Ca_0.3)TiO₃ (BZT-BCT) and La_0.7Sr_0.3MnO₃ (LSMO) have been studied. The heterostructures BZT-BCT/LSMO were …
