Effect of Mn doping on structural, morphological and dielectric properties of EuFeO₃ ceramics

Abstract

The conductivity measurements show that Mn doped EuFeO3 compounds obey Jonscher's universal power law.

Dielectric and optical properties of Ni-doped LaFeO3 nanoparticles

“…The nonexistence of any peak in tanδ defines the system as charge carrier-dominated system where the dominant contribution to polarization stems from electronic or ionic charges [53]. The similar type of behavior was also observed for EuFeO 3 [51].…”

“…This is because the electron exchange between Fe 2+ and Fe 3+ cannot follow alternating field. The dielectric constant is attributed only to the electronic polarization at very high-frequency region [51]. The electronic polarization is independent on frequency, resulting in a constant value of dielectric constant at high frequency.…”

Structural, 57Fe Mössbauer and XPS studies of mechanosynthesized nanocrystalline Nd0.33Eu0.67Fe1-Cr O3 particles

“…The physical and chemical properties of the perovskite-related europium ferrite EuFeO3 and europium chromite EuCrO3 are attractive from an applied viewpoint [1][2][3][4]. For instance the multiferroicity, low temperature canted antiferromagnetism, high dielectric constants, low dielectric losses and the high temperature stability render them potential in applications that include magnetic storage devices, spin switches, multifunctional smart devices, magneto-electric coupling devices, gas sensing devices and solid oxide fuel cells among others [1][2][3][4][5][6][7][8][9][10][11].…”

Nonhierarchical Heterostructured Fe2O3/Mn2O3 Porous Hollow Spheres for Enhanced Lithium Storage

“…Whereas, the MnO bonds (Mn 2 O 3 ) concentrated on 600–700 cm −1 become more and more strong along with the formation of heterostructured hollow spheres, which is in good agreement with ICP analysis. Notably, the peak at ≈605 cm −1 can be assigned to the vibrational modes of OFe/MnO, and it exhibits obvious Raman peak shift toward higher wavenumber region as the increase of reaction time (Figure S4, Supporting Information), which suggests that the cobonding of FeOMn emerged during the self‐assembly process . The O‐Fe/Mn‐O bonding evolution are also confirmed by the FTIR (Figure S5, Supporting Information), which can be attributed to their similar ion radius and 4d electrons status .…”
