“…[ 9 , 10 , 11 ]. Among various cation-substituted ferrites, the Mn x Fe 3−x O 4 system has long attracted the attention of researchers due to the possibility of changing the physical properties by changing the concentration of manganese, which increases the possible applications of the system [ 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 ]. Various methods of synthesizing Mn x Fe 3−x O 4 nanoparticles have been described in the literature, such as sol-gel, hydrothermal, combustion, co-precipitation, mechanochemical approaches, and so on [ 21 , 22 , 23 , 24 , 25 ].…”

Fe1.1Mn1.9O4 nanoparticles were successfully synthesized using a combustion method. The influence of the heating temperature on the evolution of the structural and magnetic properties has been studied using various methods. The structural analysis results revealed that as-synthesized nanoparticles have a tetragonal structure with an average size of ~24 nm. The magnetic measurements of the sample showed its ferrimagnetic nature at room temperature with hysteresis at low fields. Temperature-dependent magnetization measurements allowed for the conclusion that the Curie temperature for Fe1.1Mn1.9O4 nanoparticles was ~465 °C. After high-temperature magnetic measurements, during which the samples were heated to various maximum heating temperatures (Tmax.heat.) in the range from 500 to 900 °C, it was found that the structure of the samples after cooling to room temperature depended on the heating temperature. Herewith, when the heating temperature was 600 < Tmax.heat. < 700 °C, an irreversible structural phase transition occurred, and the cooled samples retained a high-temperature cubic structure. The results of the magnetic analysis showed that the samples, following high-temperature magnetic measurements, demonstrated ferrimagnetic behavior.

“…The Mn x Fe 3-x O 4 system has been actively studied over a long period [1,2] due to specific physical properties depending on its composition and great practical potential in such areas as biomedicine, lithium-ion batteries, water treatment, and supercapacitors [3][4][5][6][7][8]. This system can crystallize into two different structures: a cubic structure at x < 1.9 and a tetragonally deformed spinel structure at x > 1.9 (for bulk and single-crystal samples) [9,10].…”

In the present study, Fe1.1(CrxMn1-x)1.9O4 nanoparticles (0 ≤ x ≤ 0.5) were successfully synthesized by a combustion method, and the influence of Cr substitution on the structural and magnetic properties of the obtained nanoparticles was studied by various methods. The structural analysis revealed that the sample with x = 0 has a tetragonal structure, while all Cr-doped samples crystallize into a cubic structure. Additionally, the results of TEM show that doping with chromium leads to an increase in particle size. The magnetic hysteresis loops demonstrate the behavior typical for soft magnetic materials with low coercivity and remanence magnetization. The magnetic measurements revealed that the saturation magnetization of the obtained nanoparticles demonstrates a decreasing trend with increasing Cr content. The influence of chromium doping on the observation change in saturation magnetization is discussed. Based on the results of temperature-dependent magnetization measurements, it was found that the temperature of a magnetic transition in synthesized nanoparticles depends on Cr content.

“…Furthermore, Fe3O4 can doped with several magnetic materials, one of the material is manganese (Mn 2+ ) [10]. The transition metal cation Mn 2+ will replace the Fe 2+ atom so it will cause different properties and characteristics from Fe3O4, especially in magnetization and the magnetic moment [11,12]. Theoretically, the magnetization of the Mn 2+ ion has a 25% higher percentage compared to Fe 2+ [5].…”

Magnetic nanoparticles are a potential material that can be used in a few fields of nanotechnology such as absorbent, catalyst, energy, storage, biomedical, and cancer treatment. Every nanoparticle has different properties, so they will appear unique when two magnetic materials were composited into one unit. Mn0.25Fe2.75O4/NiCo2O4 nanocomposites were successfully synthesized by using simple coprecipitation and sonication methods. To determine the nanostructure and Specificesific Absorption Rate (SAR) value of sample, Mn0.25Fe2.75O4/NiCo2O4 nanocomposites were successfully characterized by using XRD, SEM, and Magneto-thermal instrument, respectively. Based on the data analysis, the XRD profile of Mn0.25Fe2.75O4/NiCo2O4 combining from two phase of Mn0.25Fe2.75O4 and NiCo2O4. By using the Debye Scherer equation, the particle size of Mn0.25Fe2.75O4/NiCo2O4 nanocomposites is about 10.64 nm and presentage of crystallinity is 67.66%. SEM characterization shows that there is agglomeration in the nanocomposites due to the large surface energy between the particles. Properties of superparamagnetic was observed by using VSM, saturation magnetization 17.79 emu/gr and coercivity about 0,15 T. Furthermore, SAR value of Mn0.25Fe2.75O4/NiCo2O4 nanocomposite revealed the optimum value with 0.343 Watt every gram.
