Phonon spectrum for barium ferrite

We have shown in previous work that the calculation of the intrinsic ferrimagnetic (FMR) linewidth in barium ferrite on the basis of the Kasuya-LeCraw relaxation mechanism requires a knowledge of the magnon and phonon dispersion curves far from the center of the Brillouin zone. Therefore, in this article, we have calculated the full phonon spectrum for this crystal on the basis of the rigid ...

High Technology Applications of Barium and Strontium ...

Ceramic magnets as barium ferrite or strontium ferrite have many applications in high technology. One of the reasons is the low cost when compared to competitor materials, as Alnico, MnBi, MnAl or NdFeB. In this study, the advantages and disadvantages of Ba and Sr ferrite magnets are discussed. One clear advantage is that ferrites are already oxides, and do not present the corrosion problems ...

Ferrite (magnet)

A ferrite is a ceramic material made by mixing and firing large proportions of iron(III) oxide (Fe 2 O 3, rust) blended with small proportions of one or more additional metallic elements, such as strontium, barium, manganese, nickel, and zinc. They are ferrimagnetic, meaning they can be magnetized or attracted to a magnet. Unlike other ferromagnetic materials, most ferrites are not ...
