Magnetoelectric coupling of manganese ferrite–potassium niobate lead-free composite ceramics synthesized by solid state reaction method

An effective strategy for the development of multiferroic composite nanostructures with enhanced magnetoelectric coupling performance: a perovskite–spinel approach

“…However, a small change in the lattice parameters and cell volume of the constituent phases may be due to the compressive strain between them, which is created by lattice distortion. 30 Therefore, it is worthwhile to estimate the strain ( ε ) and dislocation density ( δ ) using the following relations. 31 where β is FWHM and D is the average crystallite size, which is calculated using Scherrer's equation.…”

Enhancement of magnetic and dielectric properties of KNbO3–CoFe2O4 multiferroic composites via thermal treatment

“…A relationship between these parameters strengthens the applications of these materials in piezoelectric sensors, ferroelectric transducers, ceramic capacitors, electronic filters and magnetic data storage [3][4][5]. Extensive research has been performed to obtain ferromagnetic and ferroelectric properties in a single phase material [6][7][8][9]. Nevertheless, few materials have both of us properties in a single phase.…”

“…Potassium niobate perovskite (KNbO 3, KN) is a ferroelectric material [14][15][16] with high Curie temperature [17,18], which has been extensively studied due to its particular features in relation to electrical and optical properties [8,13,19,20]. Therefore, it attracts considerable interest in applications as sensors, transducers, and other technological fields.…”

Strain‐mediated electrical and optical properties of novel lead‐free CuFe2O4–KNbO3 nanocomposite solid solutions: A combined experimental and Density Functional Theory studies

“…At this juncture, potassium niobate (KNbO 3 ) is within the broad class of ferroelectric materials and has excellent physical properties (Birol et al, 2005; Chaiyo et al, 2011; Komalavalli et al, 2019). Nevertheless, the weak ferromagnetic behavior confines the real‐world applications associated with magnetoelectric coupling (Astudillo et al, 2015).…”
