| 摘 要： | 本文从Yoshimori-Kasai模型出发,应用slave-boson技巧,计算重费密子合金的电阻率,在平均场近似下,应用相干势近似(CPA)方法,求出合金的剩余电阻,并计入slave-boson场的涨落,解释了高浓度情况下重费密子合金出现电阻率低温极大的实验结果。关键词：

| Abstract: | The electrical resistivity of the heavy-fer mion alloy system is calculated through the Yoshimori-Kasai model with the application of the slave-boson technique. The residual resistivity of the system is found in the mean-field approximation by using the CPA method-The low-temperature resistivity maximum in the concentrated alloy is aslo obtained as the Gaussian fluctuation of the slave-boson field is included. |
