摘要: 本文研究了Fe80-xCuxSi5B15,(Fe1-xCox)82Cu0.4Si4.4B13.2两系列非晶合金的磁致伸缩系数λ4随温度T的变化关系,温度范围分别为室温至非晶态居里点和室温至晶在居里点。分析了Fe基非晶合金随温度变化所产生的结构变化,并讨论了其磁致伸缩的单离子微观机制。
Abstract: This paper studied the temperature dependence of saturation magnetostriction λ4 in both systems Fe80-xCuxSi5B15 and (Fe1-xCox)82Cu0.4Si4.4B13.2. The range of temperature is respectively from room temperature to the Curie temperature of amorphous state and to that of the crystal-line state. The structural changes following the temperature variation are analyzed, and the single-ion microscopic mechanism of magnetostriction is discussed.
