Abstract

In the recent past, a series of double-perovskite compounds with the molecular
formula of A2BB’O6 have gained keen interest among other inorganic compounds. It is due to the fact that the exhibition of large variety of physical
properties pertaining to the elements accommodated at A, B and B’ sites. In
connection to the preparation of Gd2FeMnO6, a novel single-phased double
perovskite compound has been carried out using conventional solid-state
reaction route. Rietveld refinement of powder XRD patterns reveals that the
compound crystallizes in orthorhombic crystal structure with a space group
Pbnm. X-ray photoelectron spectroscopy analysis confirms the presence of Mn
and Fe ions in ?3 oxidation state. The field emission scanning electron micrograph reveals the granular growth morphology, having grains with irregular
shape with the average grain size of about 5–10 lm. Room-temperature magnetization measurement reveals the dominant antiferromagnetic behaviour with
weak ferromagnetic interactions. Deconvoluted Raman spectra using Lorentzian
function confirm the first and second orders of Raman modes of the prepared
compound. The activation energy value of Ea = 0.16 eV obtained from the
Arrhenius plot indicates the dielectric stability of the material. The photoluminescence study shows the excitation by the light from ultraviolet region (350 to
450 nm), exhibiting blue (355 nm) to 8
S7/2 ? 6
P3/2 transition, which may provide new applications in the field of modern electronics.
