Microwave Sintering of Baryum Hexaferrite

open access: yesMRS Proceedings, 1994
ABSTRACTConventional sintering of baryum hexaferrite Co2Z leads to a mixture of phases with a low density. In this paper we try to obtain a pure densified CO2Z hexaferrite by microwave heating. The design of the applicator is computed from both the electromagnetic physical characteristics, the dimensions and the shape of the hexaferrite sample.

Investigation of Ferrimagnetic Sr-hexaferrite Nanocrystals for Clinical Hyperthermia [PDF]

open access: yesMedžiagotyra, 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.

Phase Transitions in Magneto-Electric Hexaferrites. [PDF]

open access: yesACS Omega, 2022
Hexaferrites have long been the object of extensive studies because of their great possibility for applications-permanent magnets, high-density recording media, microwave devices, in biomedicine, to name but a few. Lately, many researchers' efforts have been focused on the existence of the magneto-electric effect in some hexaferrite systems and the ...
