Theoretical study on the remanence enhancement and reversal mechanism in nanomagnets .

纳米磁体剩磁增强及反转机制的理论研究。

Currently , these models have a high magnetic remanence that make the armours release from the electromagnet after 3 seconds .

目前，这些产品有高剩磁现象，这一现象使得支架(吸板)从电磁锁上释放的时间在3秒钟之后。

Besides , by comparing magnetization reversal at saturation magnetic bias with magnetization recovery at remanence , it is found that the magnetic field applied externally does not affect the rate of domain nucleation and growth , but only their magnetization direction .

与剩磁态的激光感应超快退磁化过程比较，发现外磁场似乎并不影响磁畴结核和扩张速率，只影响磁化方向。
