| 摘 要： | 为了进一步研究磁通受交流驱动的性质,对在二维周期性钉扎系统中的磁通格子在交、直流电驱动下的动力学性质和伏安特性作了数值模拟。结果表明,在直流伏安特性曲线上出现了相锁定台阶。结构因子的数值证明沿着该台阶的磁通格子存在运动序。相锁定与交流频率和交流振幅有关,与磁通间的互作用、与磁通密度和钉扎密度等都有关。

| Abstract: | In order to investigate the behavior of vortex lattices,the dynamic property and the current-voltage characteristic of vortex lattices driven by the alternating current and the direct current are numerically simulated in two dimension periodic pinning arrays.Results show that the phase locking steps occur in the IV-curves.The moving order of vortex lattices along the step has been proved existent by the value of structure factors.The phase locking steps are related to the amplitude and the frequency of AC,the vortices interaction as well as the vortex and the pinning density. |
