Iron oxide nanoparticles: the Influence of synthesis method and size on composition and magnetic properties

Influencing factors in the CO-precipitation process of superparamagnetic iron oxide nano particles: A model based study

“…Particle mean diameters were estimated by aid of the Scherrer equation and are presented in Table 2. The mean diameters of the iron oxide nano-particles range from 3 nm to 17 nm, which is in good agreement with values reported in literature [42,48]. Results of assays 7 and 29 are not included in the DoE model.…”

Magnetic properties of ball-milled SrFe12O19 particles consolidated by Spark-Plasma Sintering

“…2b. Based on a standard X-ray database (JCPDS), the secondary phase could be assigned to magnetite Fe 3 O 4 (JCPDS number 00-019-0629), as determined from the lattice parameter, which is closer to 8.41 Å, than the maghemite (~8.34 Å)13. Refining the powder-diffraction pattern using SrFe 12 O 19 and Fe 3 O 4 results in a satisfactory fit of the data, as illustrated for SPS24 in Fig.…”

Plasma-assisted synthesis of carbon encapsulated magnetic nanoparticles with controlled sizes correlated to smooth variation of magnetic properties

“…Recent experiments have highlighted the importance of achieving better size control and smallest average sizes during synthesis of magnetic nanomaterials [16][17][18][19][20]. Samples may demonstrate smooth variation of their properties with size, only when individual samples are synthesized with sufficiently narrow size distribution in the first place.…”
