“…In other words, the thicker (than its optimised thickness) the nickel oxide layer at the interface, the weaker the interface coupling is. Comparing the maximum ME voltage coefficient of the optimised sample (90 mV/ cm•Oe) with the data from similar structures in literatures, such as 55 mV/cm Oe for the BTO thin films on metallic glass substrate using an 80 nm Au buffer layer [68] and 3.5 mV/cm Oe for BFO thin films on Ni foils [69], the higher ME in the optimised sample may be attributed to a better coupling at the interface between the BTO film and nickel substrate in some aspect.…”

Perovskite dielectric oxide thin films are tremendously important because of their promising applications in microelectronics and optic-electronic devices. Towards scalable applications of these materials, the development of wellcontrolled and cost-effective fabrication techniques is still under development. Here, recent progresses in the fabrication of perovskite dielectric oxide thin films by using a generic chemical solution deposition technique named polymer-assisted deposition (PAD) are reviewed. In this technique, metal ions are bonded to water-soluble polymers, forming stable and homogeneous precursor solutions of metallic ions surrounded by polymers which prevent hydrolysis of metal ions. Fabrication of the perovskite dielectric oxide thin films using the PAD technique, both on single crystal substrates and base metallic substrates, has been realised with good controllability. The qualities of the films are comparable with those of the ones prepared by physical-vapour deposition techniques.

“…In this way, substrate clamping effects are avoided which otherwise would hinder the propagation of strain through the heterostructure. In this respect, strain-mediated ME coupling was investigated in BFO films deposited onto Ni tapes, [109] and in Ni films deposited onto compliant polymer substrates. [106][107][108] For example, electric-field driven reversal of magnetization was observed in ferromagnetic CoFe 2 O 4 nanopillars embedded in a ferroelectric BFO matrix.…”

activities. [1][2][3][4][5][6][7][8][9][10][11][12] From a technological perspective, several low-power ME applications have been envisioned, comprising devices for memory storage and processing, [13,14] tuning and filtering of RF/microwave signals, [15,16] energy conversion and harvesting, [17,18] sensing, [19,20] and actuation. [21,22] By definition, the direct ME effect is manifested when an electric polarization P is induced by usage of a magnetic field H in accordance with Δ Δ to compare the strength of the interaction between electricity and magnetism among different magnetoelectric systems. chemical control of the physical (magnetic) properties in metals and oxide nanostructures; electrostatic doping via field-effect; reversible magnetic phase transitions induced with ionic liquid charging; spintronics; printed electronics; fabrication of solution-processed devices (transistors, etc.)There are some nontrivial reasons explaining why solid/ liquid ME composites developed later than all-solid-state approaches. From an experimental perspective, the usage of conventional aqueous electrolytes poses some restrictions in terms of the operating conditions. Concerning the applied voltage, water electrolysis already occurs at a low voltage of

“…Kimuraet al recently515 showed that the ME coupling of BFO at RT could be enhanced by the strategies such as: (a) destroying the long range spin cycloid, and/or (b) shifting the transition temperature T C or T N toward room temperature. Other attempts were made to enhance the ME coupling in BFO by: (i) construction of layered or nanosized bulk composites or multiferroic film heterostructures;[516][517][518][519][520][521][522][523][524][525] (ii) chemical substitution with diamagnetic (Ca 2+ , Sr 2+ , Ba 2+ ), rare earth (La 3+ , Gd 3+ , Nd 3+ , Dy 3+ , Sm 3+ )elements at the A-site, and magnetic (Mn 3+ , Cr 3+ ), non-magnetic dopant (Zr 4+ , Ti 4+ ) elements at B-site;294,4833,[526][527][528][529][530] (iii) formation of BFO solid solutions with other compounds;213,518,[531][532][533] and (iv) development of BFO nanoparticles with crystallite size less than the periodicity of helical order via various chemical routes 472,534.

Among the different types of multiferroic compounds, bismuth ferrite (BiFeO 3 ; BFO) stands out because it is perhaps the only one being simultaneously magnetic and strongly ferroelectric at room temperature. Therefore, in the past decade or more, extensive research has been devoted to BFO-based materials in a variety of different forms, including ceramic bulks, thin films and nanostructures. Ceramic bulk BFO and their solid solutions with other oxide perovskite compounds show excellent ferroelectric and piezoelectric properties and are thus promising candidates for lead-free ferroelectric and piezoelectric devices. BFO thin films, on the other hand, exhibit versatile structures and many intriguing properties, particularly the robust ferroelectricity, the inherent magnetoelectric coupling, and the emerging photovoltaic effects. BFO-based nanostructures are of great interest owing to their size effect-induced structural modification and enhancement in various functional behaviors, such as magnetic and photocatalytic properties. Although to date several
