在非晶态合金中,低温电阻率极小与极大值现象不仅在稀释合金中存在,而且在强铁磁性的非晶态合金中也普遍出现。我们在Fe-Cr-B,Fe-Mo-B及Fe-W-B系列中曾作了报道。本文将报道元素V对非晶态(Fe_(1-x)V_x)_(84)B_(16)合金低温电阻率的影响,并用类Kondo效应、RKKY相互作用和局部自旋涨落效应解释了不同温区的电阻率散射机制。一、实验非晶态(Fe_(1-x)V_x)_(84)B_(16)合金(x=0,0.02,0.04,0.06,0.08及0.1)采用单辊急冷法制备,带厚20—30μm,带宽约1mm。经x射线衍射结
In amorphous alloys, the low temperature resistivity and maximum phenomenon not only in dilute alloys exist, but also in the ferromagnetic amorphous alloys are also common. We have reported in the Fe-Cr-B, Fe-Mo-B and Fe-W-B series. In this paper, we report the influence of element V on the low temperature resistivity of amorphous (Fe 1-x) V x 84 alloy B 16 alloy and explain the effects of the Kondo effect, the RKKY interaction and the local spin-fluctuation effect Resistivity scattering mechanism in different temperature regions. First, the experimental amorphous (Fe_ (1-x) V_x) _ (84) B_ (16) alloys (x = 0,0.02,0.04,0.06,0.08 and 0.1) 30μm, bandwidth of about 1mm. The x-ray diffraction results
