“…The versatility of ferrite-based materials has made them applicable in various fields. Various substitutions or additions [ 30 , 31 , 32 , 33 ] of exotic metallic ions elements [ 34 , 35 ] have been made into the spinel ferrite structure in various synthesis methods such polymerized [ 36 ], hydrothermal [ 37 ], microwave combustion [ 38 ], molten salt method [ 39 ], sol-gel combustion [ 40 ] etc. Usually, spinel ferrites are produced using a standard ceramic technology method, which requires higher annealing temperatures and takes a long time for homogenization, yielding crystallites with small specific surface areas.…”

The effects of annealing temperature on the structural, physical and humidity sensing properties of stoichiometric Mg0.5W0.5Fe2O4 spinel ferrite are investigated. In order to highlight the influence of sintering temperature on the structural, magnetic and electrical properties, ferrite samples were sintered for 2 h at 850 °C, 900 °C, 950 °C, 1000 °C and 1050 °C and the physical properties and humidity influence on magnesium-tungsten ferrite materials were analyzed. X-ray diffraction investigations confirmed the formation of magnesium-tungsten ferrite in the analyzed samples. SEM micrographs revealed the influence of annealing temperature on the microstructures of the samples and provided information related to their porosity and crystallite shape and size. This material, treated at different temperatures, is used as an active element in the construction of capacitive and resistive humidity sensors, whose characteristics were also investigated in order to determine the most suitable sintering temperature.

“…Among the oxide based materials, spinel ferrites, which can be represented by the chemical formula AB 2 O 4 , are promising to fulfill these requirements. Spinel ferrite materials have been on the radar of researchers since the late 1950s due to their excellent properties like high saturation magnetization, high coercive field, moderate remnant magnetization, low eddy current losses, and high thermal and chemical stability along with their twin properties of high electrical resistivity and good magnetic conductivity. − These varieties of properties make them good candidates for various industrial applications. − …”

“…[14] Gadkari et al reported Mg 1−x Cd x Fe 2 O 4 (x = 0, 0.2, 0.4, 0.6, 0.8 and 1) with the addition of 5% Y 3+ or Sm 3+ by the oxalate coprecipitation technique. [15][16][17] They investigated the structural, magnetic and DC electrical performance of the MgCdFe 2 O 4 system by means of x-ray diffraction (XRD) and magnetic and electrical measurements. They also used Mg-Cd ferrites as gas sensors to detect liquid petroleum gas, Cl 2 and C 2 H 5 OH.…”

The combined effects of Sm3+ substitution together with the addition of 3 wt% Bi2O3 endowed the MgCd ferrites with excellent magnetic permeability and dielectric permittivity. Various concentrations of Sm3+ (x=0.00, 0.03, 0.06, 0.09, 0.12, and 0.15) were employed to modify the permeability (μ') and permittivity (ε') of the MgCd ferrites. XRD, SEM, VSM and vector network analysis techniques were used to characterize the samples. The measurement results reveal that the ferrites processed a saturation magnetization of up to 36.8 emu/g and coercivity of up to 29.2 Oe via the conventional solid-state reaction method. The surface morphology SEM confirms that with increasing Sm3+ concentration, the grain shape changes from a polygon to a circle. Moreover, the outstanding dielectric performance of dielectric permittivity can achieve 23. The excellent properties obtained in Sm3+-substituted Mg ferrites suggest that they could be promising candidates for modern high-frequency antenna substrates or multilayer devices.
