Effect of Substrates on the Structure and Ferroelectric Properties of Multiferroic ${\hbox{BiFeO}}_{3}$ Films

Recent advances in bismuth ferrite nanomaterials: Synthesis, characterization and application

“…In general, the reports in the literature focus on preparing thin film materials requiring an deposited surfaces such as LaAlO3, glass and amorphous silica substrates under encompassing various precursors routs [37][38][39][40] . For examples, the chemical vapor deposition 41,42 , pulsed laser deposition 43,44 , sputtering 45,46 , sol-gel process 47,48 and the polymeric 49,50 methods were employ to grow BiFeO3thin films. As displayed in Fig.…”

Influence of two-dimensional oxide nanosheets seed layers on the growth of (100)BiFeO3 thin films synthesized by chemical solution deposition

“…Many different deposition methods have been used to grow BFO thin films including pulsed laser deposition [9,10], chemical vapor deposition [11,12], sputtering [13,14] and chemical solution deposition using the sol-gel process [15,16] or the polymeric precursor method [17,18]. The chemical solution deposition (CSD) consists in the deposition of a solution on a substrate, typically by dip or spin coating, followed by subsequent annealing treatments of the wet film in order to crystallize the desired material [19].…”

Multiferroic properties of (Bi, Ca)FeO 3 films on glass substrates

“…Different from ceramics, ferroelectric properties are sensitive to the surface or interface structure of electrode [25][26][27][28][29][30][31][32]. In our previous studies, the refined metal bottom electrodes on glass substrates is helpful in lowering the formation temperature of perovskite phase of BFO and attaining flat dense microstructure and interface, which leads to good ferroelectric properties [25][26][27][28][29][30][31][32]. In this study, we report on Bi 1−x Ca x FeO 3 films with x = 0.05, 0.1, and 0.15 grown on refined metallic Pt(1 1 1) electrode layer buffered glass substrate by pulsed laser deposition (PLD) at reduced temperature of 450 • C. Structural, ferroelectric, and magnetic characterizations of BCFO films are presented.…”
