Structural and magnetic characterizations of coprecipitated Ni-Zn and Mn-Zn ferrite nanoparticles

Synthesis and characterization of manganese–zinc ferrite obtained by thermal decomposition from organic precursors

“…These characteristics have enabled the use of nanosized magnetic materials in biomedicine (e.g., as bioseparators), drug delivery systems, medical diagnostics, and cancer thermotherapy [5][6][7]. Due to the new applications of ferrites ways of synthesizing them, other than the ceramic method, such as the sol-gel [8,9], the precipitation [10,11], the mechanochemical [12,13], the hydrothermal [14,15], the combustion [16][17][18][19][20], and the microemulsion methods [21,22], are being widely investigated. The unquestionable advantages of the above methods are: the mixing together of the reagents at the molecular level, energy efficiency, the fact that only one process stage is required, and the absence of secondary pollution or material loss.…”

Influence of synthesis approach on structural and magnetic properties of lithium ferrite nanoparticles

“…To meet the demand of high performance devices, an important step is to synthesize ferrites in nanoscale form. Below the critical size these nanocrystals exist in a single domain state, so that the domain wall resonance is avoided and the material can perform better at higher frequency [1]. The growing interest in ferrite is due to their chemical stability, biological compatibility, relative ease of preparation and a number of applications as an electronic material associated with them.…”

Magnetic materials from co-precipitated ferrite nanoparticles

“…For magnetic particle smaller than the critical size for multi-domain formation, the domain wall resonance is avoided and the material can work at higher frequencies [3]. The recent technological advances in electronics need more compact cores for work at higher frequencies [4].…”

“…Despite the great number of papers, preparing ferrite nanoparticles suitable for new advanced applications is still a challenge [1][2][3][4][5][6][7]. Used as dispersed systems (ferrofluids) or as compact sintered materials, the ferrite particles in nanoscale can be produced by bottom-up nanotechnology approach, known as soft chemical methods, such as co-precipitation [3], sol-gel, hydrothermal synthesis [8], reverse micelle synthesis [6,9], etc.…”
