利用改进的Preisach-DOK模型模拟得到了纵向钡铁硬磁盘及γ-Fe2O3软盘的Henkel曲线和Δm曲线.研究发现钡铁氧体粒子之间具有很强的“正”相互作用,起到了阻止退磁的作用,说明钡铁氧体具有较好的剩磁特性.
利用改進的Preisach-DOK模型模擬得到瞭縱嚮鋇鐵硬磁盤及γ-Fe2O3軟盤的Henkel麯線和Δm麯線.研究髮現鋇鐵氧體粒子之間具有很彊的“正”相互作用,起到瞭阻止退磁的作用,說明鋇鐵氧體具有較好的剩磁特性.

The Henkel plot and the Am 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 △m plot, and tend to resist demagnetization, leading the oriented barium ferrite possess the unusual remanence characteristic.
