TL;DR: In this paper, an auto-combustion synthesis of Cd 2+ doped MgFe 2−x O 4 ferrite nanoparticles was reported, and the grown nanoparticles were characterized for structural properties using X-ray Diffraction technique, which confirms single phase cubic spinel structure with space group F d 3 m.

TL;DR: In this paper, silver doped Mg-Mn ferrite nanoparticles (Mg1-yMnyAgxFeFe2-xO4) are synthesized by using sol-gel technique and are characterized by X-ray diffraction (XRD), energy dispersive x-ray (EDX) analysis, field emission scanning electron microscopy (FESEM), Fourier transform infrared spectroscopy (FTIR), vibrating sample magnetometer (VSM) and Mossbauer spectrography.

TL;DR: In this paper, the replacement of Fe 3+ ions by rare-earth Nd 3 + ions and their influence on the cations distribution, structural, magnetic and Mossbauer properties of Mg-Mn nanoferrites were investigated.

Abstract: Transition metal such as Copper substituted Mn-Zn magnetic nano ferrite with general formula Mn0.5Zn0.5CuxFe2−xO4 (x = 0.0, 0.1, 0.2, and 0.3) were fabricated by solution combustion method and expose how significant properties of the samples are modified accordingly by dopant concentration. By FTIR spectroscopy various functional group present in Mn-Zn ferrites is studied. The optical plots revealed bandgap energy reduced from 2.42 to 1.82 eV although the electrical study shown the highest conductivity of synthesized nano ferrite is 1.93 × 10−8Scm−1. The dielectric constant as well as dielectric loss behavior recorded at room temperature and were analyzed with increasing temperature; both dielectric constant and loss tangent upsurge however with increasing frequency both are observed to reduce. Doping with Cu has the potentiality of accumulative dielectric constant and conductivity of Mn0.5Zn0.5CuxFe2−xO4 thereby improving its application for electromagnetic devices.

TL;DR: In this paper, the structural, cation distribution and magnetic properties of the synthesized nanoferrites have been explored using X-ray diffraction, vibrating sample magnetometer (VSM) and Mossbauer spectroscopy techniques.
