Different iron oxides (i.e., magnetite, maghemite, goethite, wüstite), particularly nanosized particles, show distinct effects on living organisms. Thus, it is of primary importance for their biomedical applications that the morphology and phase-str

Nanocrystalline 2:14:1-type Ce–Fe–B alloy powders show potential application for low-cost hard magnets, but it is still a big challenge to prepare bulk anisotropic Ce–Fe–B magnet. In this study, we investigated the fabrication of bulk Ce–Fe

The sol-gel process was used to produce ferrite Ni0.3Zn0.7Cr2−xFexO4 compounds with x = 0, 0.4, and 1.6, which were then subsequently calcined at several temperatures up to 1448 K for 48 h in an air atmosphere. X-ray diffraction (XRD), scanning ele
