Electrical and magnetic properties of spherical SmFeO 3 synthesized by aspartic acid assisted combustion method

Effect of Zr addition on structure and electrical properties of SmFeO3 prepared by solid state reaction method

“…FullProf software [36] was used to perform the Rietveld refinement of the XRD data. The least-square refinement was converged with the minimum goodness of fit (χ 2 ) and agreed with the literature data [16,17,21]. Scanning electron microscope (SEM-JSM-7610F) was used to investigate microstructure of the sintered samples.…”

“…One of the interesting materials for these applications is doped SmFeO 3 . Therefore, investigation of the structure of Zr-doped SmFeO 3 [15][16][17] can measure the possibility of their application in energy devices with high stability based on the presence of Zr 4+ in the structure.…”

Electrochemical and magnetic properties of electrospun SmFeO3 and SmCoO3 nanofibers

“…Rare earth perovskite oxides (RMO 3 , M = transition metals) have attracted intense interest due to their outstanding electrochemical, electrical, catalytic, and magnetic properties, and have been extensively applied in energy storage devices, chemical sensors, catalysis, and spintronics 1–7 . Generally, RMO 3 type structure consists of an R 3+ cation in the body center and eight MO 6 octahedra at the summits.…”

“…In previous research, the magnetic and electrical behaviors of some simple and complexed perovskite oxides, such as Y 3 Ba 5 Cu 8 O 18±δ , YBa 2 Cu 3 O 7‐δ , (1‐x)BaTiO 3 /xSr 0.92 Ca 0.04 Mg 0.04 Fe 12 O 19 composite, (BaTiO 3 ‐SrTiO 3 )/WO 3 composite as well as SrFe 11.96 V 0.04 O 19 /Ni 0.5 Mn 0.5 Fe 2 O 4 nanocomposite, were investigated in detail 9–12 . Samarium iron oxide (SmFeO 3 ) possesses remarkable magnetic characteristics, favorable p‐type semiconducting property, and outstanding gas‐sensitivity 5,6 . SmFeO 3 has distorted orthorhombic structure with space group Pnma(62) and FeO 6 octahedron tilted toward Sm 3+ cation to sustain the Sm‐O bonding 5,13 .…”

“…The electrochemical properties of SmCoO 3 decorated reduced graphene oxide as supercapacitor electrode were investigated, and this material exhibited a good energy and power density, as well as a favorable retention property 16 . The previous fabrication approaches of SmFeO 3 and SmCoO 3 include citric acid method, 13 thermal treatment, 6,7 and combustion method 5 . These methods have the disadvantages of long reaction time and high reaction temperature.…”
