In this paper, the detailed study of magnetic properties of Dy3+ substituted soft manganese ferrite (MnFe2O4) nanoparticles with varied contents of Dy3+ ions (0.00 ≤ x ≤ 0.16) was carried out by vibrating sample magnetometery (VSM) at room temperature. The synthesis of reported magnetic materials was carried out via facile wet chemical route. Structural characterization was investigated via X-ray diffraction and infra-red spectroscopy. Exploration of magnetic measurements revealed an irregular behavior in the values of saturation magnetization (Ms), remanent magnetization (Mr), and coercivity (Hc) depending upon the concentration of rare-earth ions (Dy3+). The fluctuations in the values of Ms, Mr, and Hc may be associated with the modifications in the spin-exchange interactions caused by structural changes due to the substitution of rare-earth ions (Dy3+). DC electrical resistivity values were recorded and were found to be increased with increased Dy3+ contents. The soft magnetic nature of Dy3+ substituted MnFe2O4 spinel ferrites nanoparticles suggested their possible utilization in switching mode power supplies, recording media, spintronics, and many other advanced technological devices.

“…It is observed that an increase in the amount of Eu (x = 0.15) content result in an increase in the coverage of the grains by the EuFeO3 phase and this is beneficial to grain growth. Figure 3 shows, the imaginary component µ'' first rises slowly and then increases quite abruptly making a peak at a certain frequency where the real component µ' is falling sharply [17]. This feature is well known as the ferromagnetic resonance [21].…”

Article HistoryThe present work is focused on the influence of substitutions rare earth europium ions (Eu 3+ ) in soft poly crystalline Ni-Zn ferrites. A series of ferrite samples of the compositions Ni0.60Zn0.35Eu0.05Fe2O4, Ni0.60Zn0.30Eu0.10Fe2O4 and Ni0.60Zn0.25Eu0.15Fe2O4 were prepared by using double sintering solid state reaction technique. The presintering and sintering were performed at temperature 1000 0 C for 3 hours and 1250 0 C respectively. The phase identification was carried out by using the X-ray diffraction (XRD). The XRD analysis revealed that undoped rare earth in sample shows formulation of cubic spinel structure with no extra peak but Eu 3+ doped samples show additional peaks other spinel structure and corresponding to a second orthoferrite phase. A slightly increase in bulk density has been found with increasing RE content. The average grain size increases significantly with increasing Eu 3+ content. The increase in density and grain growth of the samples may be attributed to the liquid phase at constant sintering temperature. Saturation magnetization, Ms was observed and was found to increase with increasing, Eu 3+ contents. Eu 3+ substitution in the NiZn ferrites leads to increase of Fe 3+ ions on the B-sites and consequently decreases Fe 3+ ions on A-sites which lead to the increase in saturation magnetizations. The change of Ms with the augmentation of Eu 3+ substitution has been explained on the Neel's Collinear two sublattices magnetization model and Yafet-Kittels' non-collinear magnetization model. It is observed that addition of the rare earth europium ions (Eu 3+ ) in polycrystalline Ni-Zn rare earth ferrites play an important role in modification of structural and magnetization characteristics.Contribution/ Originality: The paper's primary contribution is finding that this can be used as magnetic materials for transformer due to the stability of permeability for a high frequency range. Moreover, by studying the literature it is seen that it can be used as anode or cathode materials for Lithium Ion Batteries (LIB).
