摘要：

Galvanomagnetic effect of NiFe rings has been studied, It was found that the ring takes two kinds of magnetization state, closure domain state and bi-domain state. At very low temperatures, resistance oscillation and fluctuation were observed, indicating the existence of the quantum interference effects such as Aharanov-Bohm effect.
