衍射模型对非晶态Fe－Co合金适用的温区

Diffraction Model Temperature Range of Applicable to Amorphous Fe- Co Alloys

研究了非晶态合金（Ｆｅ（１－ｘ）Ｃｏｘ）８２Ｃｕ０．４Ｓｉ４．４Ｂ１３．２（ｘ＝０．０２，０．０５，０．１０，０．１５）的电阻率和温度之间关系，样品的德拜温度在３５０～５３０Ｋ之间，在１１Ｋ（Ｔ＜１００Ｋ和２００Ｋ以上的温区，电阻率分别与温度平方户和温度Ｔ成线性关系，在１１Ｋ＜Ｋ２００Ｋ的温区内，样品的导电机制可用衍射模型描述．

The relationships between the resistivity of the amopohous alloys(Fe1-xCox)82 Cu0.4 Si4.4 B13.2(x=0,0.02,0.05,0.10,0.15)and temperature are studied in this paper. The Debye temperature lies between 350～530 K,The resistivitv varies with T2 in the interval of 11 K<T<100 K and with T in the range of 200 K<T<300 K,The electronic transport mechanisrns will be des cribed by the diffraction model in the temperature range of 11 K<T<200 K。
