Improved Preisach-DOK Modeling on the Henkel Plot of a Longitudinal Barium Ferrite

Article Preview

Abstract:

The Henkel plot and the Δm plot of a longitudinal barium ferrite hard disk and γ-Fe2O3 flexible disk were simulated by the improved Preisach-DOK model.The study results show that the barium ferrite exhibit large positive interactions, as shown by large positive in the Δm plot, and tend to resist demagnetization, leading the oriented barium ferrite possess the unusual remanence characteristic.
