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.

Review on Y-type hexaferrite: Synthesis, characterization and properties

Applied Surface Science Advances, 2023
Ferromagnetic properties of hexaferrites induce magnetisation inside their crystal structure, separating them into uniaxial and ferroxplana hexaferrites. Y-type is the first observed ferroxplana ferrite with spontaneous magnetization in the basal c-plane

Adaptation of the Crystal Structure to the Confined Size of Mixed-oxide Nanoparticles

Acta Chimica Slovenica, 2022
Chemical composition and crystal structure are central to defining the functional properties of materials. But when a material is prepared in the form of nanoparticles, the structure and, as a consequence, the composition will also frequently change ...
