| 摘 要： | 研究了(Fe1-xWx)84.5B15.5(x=0—0.1)非晶态合金的电阻率ρ与温度T(4.2—300K)的关系。实验结果表明,在所研究浓度区域内均出现电阻率与温度关系的极小值,电阻率极小值的温度Tmin在x=0.06时出现峰值。用x=0.02—0.1浓度区域内,当Tmin时,又出现了电阻率与温度关系的极大值,电阻率极大值的温度Tmax在26—35K之间。低温电阻率反常现象与类Kondo效应及局域磁矩之间RKKY相互作用有关。

| Abstract: | The electrical resistivity of amorphous(Fe1-xWx)84.5B15.5(x = 0—0.1) alloys has been studied as a function of temperature between 4.2 and 300 K. The resistivity minima was observed over the whole concentration range, and the temperature of resistivity minimum Tmin showed a peak at x=0.06. Below Tmin the resistivity showed maxima in the range x=0.02—0.1. The temperature of resistivity maximum Tmax is between 26 and 35 K. The low temperature resistivity anomaly may originate from Kondo-like effect and RKKY interaction between localized magnetic moment. |
