Electrochemical and magnetic properties of perovskite-type PrFeO3 and EuFeO3 nanofibers

Uniform rare earth orthoferrites (PrFeO 3 and EuFeO 3 ) nanofibers have been synthesized. The fabricated samples possessed an orthorhombic perovskite structure. The average diameters of PrFeO 3 and EuFeO 3 samples were approximately 233 and 176 nm, respectively, and the morphologies were uniform and...

Description
Summary:Uniform rare earth orthoferrites (PrFeO 3 and EuFeO 3 ) nanofibers have been synthesized. The fabricated samples possessed an orthorhombic perovskite structure. The average diameters of PrFeO 3 and EuFeO 3 samples were approximately 233 and 176 nm, respectively, and the morphologies were uniform and continuous nanofibrous structures. The pseudocapacitive performances of PrFeO 3 /EuFeO 3 were attributable to the oxidation-reduction reactions of Fe 3+ /Fe 4+ and Fe(CN) 6 3− / Fe(CN) 6 4− . PrFeO 3 and EuFeO 3 nanofibers showed the specific capacitances of 123 and 143 F g −1 at 1 A g −1 , respectively. The magnetic properties of PrFeO 3 and EuFeO 3 nanofibers were investigated. PrFeO 3 nanofibers presented stable magnetic behaviors. EuFeO 3 nanofibers showed a spin-glass state transition phenomenon. This research suggested that PrFeO 3 and EuFeO 3 nanofibers could be effectively and feasibly applied in supercapacitors and condensed matter physics.
