γ-Fe2O3 by sol–gel with large nanoparticles size for magnetic hyperthermia application

Effects of γ-Fe2O3 on γ-Fe2O3/Fe3O4 composite magnetic fluid by low-temperature low-vacuum oxidation method

“…Both of these shortages have restricted the applications of Fe 3 O 4 magnetic fluid [10][11]. The γ-Fe 2 O 3 nanoparticles have been widely used in various magnetic recordings and storage medium due to its excellent magnetic properties and chemical stability over the past years [12][13]. It is because that γ-Fe 2 O 3 grain comes into nano-size, it gets more excellent magnetic properties than the usual structure, its coercive force is also greatly improved, the magnetic recording materials made by the γ-Fe 2 O 3 powder can significantly improve the signal-to-noise ratio and improve image quality, and can achieve highdensity information recording.…”

Variations in magnetic properties caused by size dispersion and particle aggregation on CoFe2O4

“…However, in most of the cases, this route produces nanoparticles with a broad range size dispersion and heavy aggregation [17]. Most papers usually just report a histogram with a standard deviation (σ) to show how much the sample deviates from monodispersion, as truly monodisperse samples are rare and considerably difficult to achieve [24]. In addition, the aggregation influence on the magnetic properties measured for the overall material is rarely considered to explain the magnetic results [4,27,33].…”

Synthesis and characterization of Ni–Cu alloy nanoparticles with a tunable Curie temperature

“…Today, the use of magnetic nanoparticles (mostly iron oxide) prevails in various technological and biomedical applications, for example, forward osmosis [3], cellular labeling, magnetic separation, drug delivery [4][5][6], and magneticmediated hyperthermia. One of the most promising uses of magnetic nanoparticles in biomedicine is as a cure for cancer with the use of magnetic-mediated hyperthermia (which is currently in clinical trials) [7][8][9][10]. At present, iron oxide superparamagnetic nanoparticles are the only magnetic nanoparticles that are approved for in-vivo applications [11].…”
