Strong magnetoelectric coupling in sol–gel derived multiferroic (Pb0.76Ca0.24)TiO3–CoFe2O4 composite films

Preparation of LSMO/PLZT Composite Film by Sol-Gel Technique and its Ferroelectric and Ferromagnetic Properties

“…While, sol-gel technique is widely adopted due to its low cost, ease in adjustment of the chemical composition and the ability of large area deposition. Moreover, in order to fabricate the composite film with an enhanced ME coupling effect, the ferromagnetic phase with a large magnetostrictive effect and the ferroelectric phase with a large piezoelectric effect are needed [10][11][12]. In the present work, considering the low resistivity and the greater magnetostrive coefficient of La 0.67 Sr 0.33 MnO 3 (LSMO), it was selected as a ferromagnetic phase and was deposited on the (001) LaAlO 3 (LAO) substrate by the Sol-gel technique.…”

Ferroelectric and structural instability of (Pb,Ca)TiO3 thin films prepared in an oxygen atmosphere and deposited on LSCO thin films which act as a buffer layer

“…Among them, the solid solution of Pb 1À x Ca x TiO 3 (PCT) is a well known ferroelectric material [7,8] and is regarded as a promising material for piezoelectric sensors and uncooled pyroelectric infrared detectors. Recently, much research has been devoted to the preparation of PCT thin films on oxide single crystal substrates such as SrTiO 3 , LaAlO 3 , SiO 2 and MgO by various deposition techniques to investigate their structural, microstructural, optical and ferroelectric properties [9,10].…”
