| 摘 要： | 利用改进的DOK模型模拟了纵向BaFe硬磁盘的磁滞回线、剩磁回线以及Henkel曲线,计算了它的剩磁矫顽力(Hr)、剩磁矫顽力方矩(Sr3)、剩磁开关场分布(SFDr)和剩磁回线的斜率(SP75)。模拟得到与实验结果符合得很好的磁滞回线,并且将纵向BaFe硬磁盘的Sr3、SFDr、SP75和Henkel曲线t与其它磁记录材料的相应参数做了比较。

| Abstract: | The hysteresis loop,the remanence hysteresis loop and the Henkel pl ot of a longitudinal barium ferrite(BaFe)hard disk were simulated by the impro ved DOK model.Simultaneously,the remanence coercivity(Hr),the remanence squa reness(Sr),the remanence switching field distribution(SFDr),the slope of t he remanence curve(SP75)were calculated.The simulated results were in good ag reement with experiment results,and the remanence parameters(such as Sr,SFD r,SP75 and Henkel plot)of the longitudinal BaFe hard disk were compared with t hose of other magnetic recording media. |
