【摘要】 在80—380K之间对(Fe_1-xCr_x)₈₄B₁₆（x=0.01—0.46）非晶态合金的绝对热电势S进行了测量,结果表明,磁性非晶合金的S（T）行为并不都是非线性并有一个浅的极小。少量Cr（x≤0.05）的加入使S的绝对值减小,并使S（T）的极小消失;当Cr含量较多时,样品磁性变弱,S（T）从典型的磁性非晶合金的非线性行为过渡到接近于非磁性非晶合金的线性行为。对x=0.15,0.25的样品,其居里点正落在我们测量的温度范围内,经过仔细的测量,在居里点T_c附近没有看到S的反常。更多还原

【Abstract】 The absolute thermoelectric power S of amorphous metallic alloys （Fe1_xCrx）84B₁₆ has been measured as a function of temperature in the range of 80 to 380 K for 0.01≤x≤0.46. It is found that the behavior of S（T） for the magnetic alloys does not always follow a nonlinear variation law with a shallow minimum. The. addition of a small amount of Cr （x≤0.05） is shown to lower the absolute value of S and wash out the minimum. With a larger Cr content, the alloys are weakly magnetic and the behavior of S（T） changes from nonlinear, typical of magnetic amorphous alloys, to nearly linear, similar to that for nonmagnetic alloys. A value of x of 0.15 and 0.25 is not found to have any effect on the value of 8 at the Curie temperature Tc, which happened to he in our working temperature region.更多还原
