Hydrothermally prepared nanocrystalline Mn–Zn ferrites: Synthesis and characterization

Effect of Sn–Ni substitution on the structural, electrical and magnetic properties of mixed spinel ferrites

“…Drift mobility ( d ) is calculated from electrical resistivity data using the following relation [15][16][17]:…”

“…Several cations such as Zn 2+ , Cu 2+ , Co 2+ and Ti 4+ have been attempted by several researchers in order to improve the electrical and magnetic properties of manganese ferrites [13][14][15][16][17][18][19]. Ti 4+ substitution at iron site in manganese ferrites is known to be effective in reducing magneto crystalline anisotropy and enhancing the electrical resistivity, these properties are suitable for wide range of * Corresponding author.…”

A comparative study of in-situ mechanochemically synthesized Mn0.5Zn0.5Fe2O4 ferrite nanoparticles in the MnO/ZnO/Fe2O3 and MnO2/Zn/Fe2O3 systems

“…This confirms the reduction and oxidation of the Mn. In fact, the Mn 2 þ to Mn 3 þ or Mn 4 þ oxidation would occur in the temperature range around 200-400 1C, which is accompanied by weight gain in the TG curve [11]. A reduction of Mn 4 þ to Mn 3 þ occurs in the heating temperature range around 400-650 1C, which causes a weight loss in the sample.…”

The study of thermal, microstructural and magnetic properties of manganese–zinc ferrite prepared by co-precipitation method using different precipitants

“…The bottom-up nanotechnology approach, including soft chemical method, allows to synthesize homogeneous materials with defined morphology. Among these methods, especially sol-gel autocombustion [1][2][3][4][5][6], coprecipitation [7,8], the hydrothermal and solvothermal [9][10][11], the reverse micelles [12] and the mechanochemical [13] methods have been extensively studied in the last years. Ferrite produced by chemical methods is often characterized by unique properties suitable for new advanced application, i.e., magnetic high-density information storage or drug delivery or contrast agent in biomedicine [14][15][16][17][18].…”
