Abstract

Two series of octahedral Fe3-xZnxO4 nanoparticles with mean sizes of 27 nm and 73 nm were prepared by thermal decomposition. All samples crystallize in inverse spinel cubic type structure with the Zn2+ ions located in tetrahedral sites. Magnetic measurements indicate an increase of the saturation magnetizations by 20% for a Zn content of x=0.12. The estimated anisotropy constants are close to that of pure magnetite. The physical properties of the investigated series are analysed in correlation with their structural properties..
