【摘要】 在室温到１５Ｋ范围内我们对Ｎｉ／Ｗ金属超晶格的输运性质进行了测量．随温度的降低，反常的电阻跳跃被发现，这种现象被归因于Ｎｉ／Ｗ超晶格样品从晶态到非晶态的结构相变．温度降低时，样品界面处的原子无序度增大，当这种无序积累到一定程度时样品发生从晶态到非晶态的结构相变．更多还原

【Abstract】 Abstract Transport properties of Ni/W superlattices have been studied between 15K and room temperature. With the decrease of temperature, an anomalous jump of resistance has been found which results from a structural transition from crystalline to amorphous in Ni/W samples. This type of transition is interpreted by atomic disorder present at interfaces and when temperature decreases the defect concentration increases until the sample undergoes a crystalline to amorphous transition.更多还原
