摘要：

The reversal of spontaneous magnetization of a superconducting pi 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.
