自发磁化的超导π环在电触发下的行为

The reversal of spontaneous magnetization in high T_c superconducting π rings

运用Runge Kutta四步积分法分析了一个双结π环电路在输入脉冲电流触发下自发磁化电流的翻转过程 .发现在适当的参数条件下 ,输入周期性脉冲 ,π环环流会产生周期性翻转现象 ,由正到负和由负到正的翻转将产生不同的输出脉冲 .

The reversal of spontaneous magnetization of a superconducting π ring under a pulse current injection has been thoroughly analyzed with the fourth ordered Runge Kutta method. We find that the reversals from negative to positive and from positive to negative will produce different pulse output with a periodic pulse injection and some certain parameters which can give a checkout of directions of the spontaneous magnetization as well as the phenomena of reversal under pulse injection.
