Structural and magnetic properties of manganese zinc ferrite nanoparticles prepared by solution combustion method using mixture of fuels

Abstract

The structural analysis and magnetic investigation Mn 1 À x Zn x Fe 2 O 4 with stoichiometry (x ¼ 0, 0.1, 0.3, 0.5, 0.7, 0.9 and 1.0) were synthesized by solution combustion method using mixture of fuel this is first of its kind. As synthesized Mn-Zn nanoferrites were characterized by X-ray Diffractometer (XRD), Transmission electron microscopy (TEM) at room temperature. The magnetic domain relaxation was investigated by inductance spectroscopy (IS) and the observed magnetic domain relaxation frequency (f r ) was increased with the increase in grain size. The Room temperature magnetic properties were studied using vibrating sample magnetometer (VSM). It was observed that the real and imaginary part of permeability (μ′ and μ″), saturation magnetization (M s ), remanance magnetization (M r ) and magneton number (M r /M s ) were decreases gradually with increasing Zn 2 þ concentration. The decrease in the saturation magnetization may be explained as, the Zn 2 þ concentration increases the relative number of ferric ions on the A sites diminishes and this reduces the A-B interaction. Hence synthesized materials are good for high frequency applications.

Structural, multiferroic properties and enhanced magnetoelectric coupling in Sm1−xCaxFeO3

“…According to the Stoner-Wohlfarth model [53], M r /M s for an assembly of non-interacting 3D random particles is given by M r /M s ¼0.5 for uniaxial anisotropy and M r /M s ¼0.832 for cubic anisotropy. In the present study we obtained high M s compared to the earlier reports [13] as the magnetic properties depend on the method of preparation, microstructure and density [54].…”

“Ferrites”: Synthesis, Structure, Properties and Applications

“…The fuel chosen has a very important effect on ferrite prepared. The fuel in this process is either urea or glycine [37,38] or their mixture [39]. By balancing the oxidising (O) and reducing valency (F) of the reactants, the Stoichiometry ɸe = (O/F) is maintained at unity.…”

“…3 Previous studies pointed out that the surface, size, crystallinity, morphology, and composition strongly correlate with the physicochemical properties of spinel ferrite materials. [9][10][11][12][13] Moreover, these properties are inuenced by some advanced parameters such as dimension, dispersion, and surface area which can be changed by combining with various nanomaterials. [13][14][15][16][17] For the aim of enhancing the inherent characteristics, many spinel ferrite-based nanocomposites have been fabricated for boosting their diversity applicability from environmental, biomedical, and sensors to biotechnology applications.…”
