Electrical properties of samarium cobaltite nanoparticles synthesized using Sol–Gel autocombustion route

Electrochemical and magnetic properties of electrospun SmFeO3 and SmCoO3 nanofibers

“…The existence of Sm 2 O 3 might be attributed to the incomplete perovskite phase formation during the calcination process. From the pattern of SmCoO 3 , all the peaks are highly consistent with JCPDS card (25‐1071), demonstrating that the synthesized sample possesses the orthorhombic perovskite structure with space group Pbnm(62) 3 . In addition, no characteristic impurity phase is detected, proving the phase purity of SmCoO 3 NFs.…”

“…As shown in Figure 3E, Co possesses Co 2+ , Co 3+ , and Co 4+ valence states. In Co spectrum, the major peaks at 779.89 and 794.88 eV are attributed to Co 2p 3/2 and Co 2p 1/2 , as well as the satellite peaks locate at 789.81 and 804.18 eV, respectively, manifesting the presence of Co 3+ and Co 2+ states 3,33 . The weak peak at 782.63 eV is indicative of the formation of Co 4+ state 33 .…”

“…Samarium cobalt oxide (SmCoO 3 ) possesses outstanding electrocatalytic property, excellent chemical stability, and high electrical conductivity 7,14 . Similar to SmFeO 3 , SmCoO 3 has distorted orthorhombic structure and tilted CoO 6 octahedron 3,15 . He et al.…”

“…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.…”

Structural, magnetic and electrical analysis of La1−x Nd x CrO3 (0.00 < x < 0.15): synthesised by sol–gel citrate combustion method

“…It is observed that at high temperature, long range motion of charge carriers is indicated by the plateau region measured at temperature 453 K. On fitting the single power law for all the Nd-substituted samples, the exponent n from the fit is found to be less than 1. The n value less than 1 indicates the hopping motion involves translation with a sudden hopping [51]. This infers that the translation motion with hopping is present in all the samples of Nd-substituted LaCrO 3 .…”
