Abstract

A novel multiferroic thin-film heterostructure exhibiting both ferromagnetic (FM) and ferroelectric (FE) properties, as well as magneto-optic (MO) and electro-optic (EO) properties, was fabricated via a wet chemical route. Oxide buffer layers were used to allow the growth of ferroelectric lanthanum modified lead magnesium niobate titanate (La:PMNT) layer on top of ferromagnetic bismuth and aluminum substituted yttrium iron garnet (BiAl:YIG). X-ray diffractometer (XRD) analysis confirmed the formation of both crystalline structures. Scanning electron microscopy (SEM) and atomic force microscopy (AFM) were used to examine the surface and cross-section morphologies of the resulted heterostructure. Multiferroic properties of the film were investigated.
