The effect of magnetic interaction in barium hexaferrite particles [PDF]

Journal of Applied Physics, 1997
The effect of interactions on the magnetic relaxation of nanocrystalline hexagonal barium hexaferrite BaFe10.4Co0.8Ti0.8O19 is discussed. We had previously shown that according to the T ln(t/τ0) scaling, an enhancement of the lowest-energy barriers was detected when demagnetizing interactions were dominant. Also, the Henkel plots obtained for particles

Microscopic Mechanism of Ferroelectric Properties in Barium Hexaferrites

SSRN Electronic Journal, 2022
The microscopic mechanism of the occurrence of ferroelectric properties in M-type barium hexaferrites is investigated by experimental and first-principle computation methods. The analysis of magnetic, X-ray, and Mössbauer measurements of BaFe12O19 samples ascertains the correlation between the thermal factor in the process of annealing samples and ...
