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.

The structural, magnetic, dielectric, and surface morphology of BiSn x Fe 1-x O 3 (x = 0.0 to 1.0) was analyzed experimentally. The samples were synthesized by a simple chemical micro-emulsion method. The X-ray diffraction (XRD) analysis reveals structural distortion at A site and B site of BFO due to Sn doping in rhombohedral phase. The EDX data certify Sn is well incorporated in BiFeO 3 . The effect of Sn doping on crystal size and grain size has also been addressed. The FTIR analysis elaborates absorption at 555 cm −1 which is due to stretching and bending vibrations of O-Fe-O bonds. The magnetic properties are illustrated by vibrating sample magnetometer (VSM). The magnetic moments and exchange mechanism described theoretically by DFT analysis which support the experimental results. The dielectric behavior of studied materials has been evaluated by dielectric constant (ɛʹ), tangent loss (tanδ), real and imaginary part of impedance, and Cole-Cole plots in 1-3 GHz. The spin-orientated magnetism and dielectric response increase their potential for microwave absorber and sensor.Keywords Room temperature ferromagnetism • Micro-emulsion method • Vibrating sample magnetometer * Q.

“…, where = C 0 ∕C . [61] There is evidence to suggest that when the frequency of the applied electric field increases, the value of the real modulus (M′) increases while the imaginary modulus (M′′) decreases. Thus, the studied sample exhibits a thermally activated relaxation process, as demonstrated by our electrical modulus results.…”

In this communication, the synthesis and characterizations of modified strontium manganate (SrCu1/3Mn1/3W1/3O3) (SCMWO) by high‐temperature solid‐state method are reported. The structural analysis predicts a monoclinic structure with a crystallite size of 36.8 nm. The analysis of the Raman active modes reveals the presence of all the constituent atomic vibrations. The study of the ultraviolet–visible spectrum provides a bandgap energy of 1.71 eV, which may be suitable for photovoltaic applications. A Maxwell‐Wanger type of polarization effect is observed at low frequency while low dielectric loss makes the material suitable for energy storage devices. The study of the impedance plots reveals the negative temperature coefficient of resistance (NTCR) character. The activation energy increases with both frequency and temperature in the modified perovskite suggesting that conductivity of the sample increases and material characters are changing from dielectric to semiconducting. The symmetrical curves in the electrical modulus plots and shift toward higher frequency region agree with the results of the non‐Debye‐type of relaxation mechanism. The semicircular curves in the Cole–Cole plots confirm the semiconducting nature and are also well supported by the results of Nyquist plots. The studied material exhibits a semiconductor nature, which may be found suitable for energy storage device applications.
