Investigation of Ferrimagnetic Sr-hexaferrite Nanocrystals for Clinical Hyperthermia

Medžiagotyra, 2021
Sr-hexaferrite samples were produced via the conventional ceramic method. X-ray diffractometry (XRD) patterns confirmed the single nanocrystal phase as Sr-hexaferrite where any pattern peaks of unreacted Fe2O3 phase were  not detected.

CoFe2O4 bulk, nanoparticles and layer: A comparison of structural, magnetic, and optical properties [PDF]

Progress in Physics of Applied Materials, 2022
The structural characteristics of materials change with the reduction of dimensions, and they show different behaviors compared to the corresponding bulk sample. To study these changes, in this research, we investigated the effect of size and preparation
